According to forum posts, it's recommended to choose islands within the same group for easier travel, such as the Cyclades or the Ionian islands. This minimizes transit time and maximizes time spent enjoying the islands.

Some travelers have noted that ferries are a common mode of transportation between islands. However, they also mentioned that ferry schedules can be infrequent and vary by season, which could affect travel plans.

For faster travel between islands, especially those not in the same group, several posts suggested considering flights. Direct flights between major islands like Corfu and Kefalonia are available and can be a quicker option than ferries.

Travelers have called out the importance of checking and planning itineraries carefully when island hopping in Greece due to potential delays and limited transport options between some islands. This is crucial to ensure smooth transitions and avoid losing valuable vacation time.

Some travelers expressed a preference for quieter, less commercialized islands with natural beaches. They highlighted the importance of accessibility to these beaches either by foot or public transport, emphasizing a desire for peace and quiet over bustling tourist spots.

According to forum posts, Naxos and Crete were frequently recommended for their beautiful beaches and natural settings. Naxos, in particular, was praised for its scenic beauty and suitability for activities like snorkeling and hiking, making it a good choice for a beach vacation. Crete, being larger, offers a variety of beaches ranging from quiet coves to more developed areas.

Travelers have called out that visiting during the shoulder seasons like May or September could enhance the experience by avoiding the peak tourist crowds. This timing helps in enjoying the natural beauty of the islands more peacefully.

Some travelers recommended focusing on fewer destinations to minimize transit times and maximize relaxation. For instance, a family-friendly itinerary could involve flying into Athens, spending a few days there, then visiting islands like Naxos or Crete, which offer a mix of beaches, historical sites, and child-friendly activities. Naxos, in particular, was highlighted for its beauty and less crowded environment compared to Mykonos.

According to forum posts, Crete and Naxos are top recommendations for families. Crete is large enough to offer diverse activities and has a reliable public transport system, while Naxos provides a calm atmosphere with plenty of beaches and local culture. Both islands are large enough to explore over several days without feeling rushed.

Travelers have suggested that renting self-contained apartments might be more comfortable for families, offering space and the convenience of cooking meals. This option is also seen as more budget-friendly compared to hotels, especially for longer stays.

According to forum posts, multiple ferry companies operate between the Cyclades islands. Blue Star Ferries serves the Central Cyclades, including Paros, Naxos, Ios, and Santorini, as well as the Small Cyclades. Fast Ferries and Golden Star Ferries are options for the Northern Cyclades, such as Andros, Tinos, and Mykonos. For the Western Cyclades, including Serifos, Sifnos, Milos, Kimolos, and Folegandros, Zante Ferries is recommended.

Some travelers have mentioned that Hellenic Seaways, part of the same group as Blue Star Ferries, offers a loyalty program called Seasmiles, which may be beneficial for those using their services frequently. Additionally, Express Skopelitis provides daily connections (except Sundays) between the Small Cyclades and Naxos.

For the cheapest ferry options in the Cyclades, the government-subsidized Inter Cyclades routes of the Artemis (operated by Hellenic Seaways/Blue Star Ferries) are highlighted. However, it's important to note that some of these routes run only once a week.

Travelers suggest buying ferry tickets at local ticket offices as you travel, allowing for flexibility in your itinerary. This is viewed as the best way to manage payments for ferry travel over an extended period.

According to forum posts, many travelers recommend Santorini for its unique landscapes and the caldera view. Crete also comes highly recommended for its beaches and historical sites, particularly in the western part which is less touristy.

Travelers have called out Athens for its rich historical significance, with the Parthenon being a must-visit. Delphi is also noted for its archaeological site and museum, offering a deep dive into ancient Greek culture.

For a blend of beautiful beaches and cultural experiences, Naxos is frequently suggested. It offers great beaches, hiking opportunities, and a taste of authentic Greek village life.

Several travelers have recommended Athens Car Rentals and Auto Union as reliable options for renting a car at Athens International Airport. These companies have been praised for allowing cars to be taken to islands, which many other rental firms do not permit.

ACR (Athens Car Rentals) has been highlighted for its efficient service. It does not have a physical office at the airport but meets customers at the arrivals to deliver the car. Users have mentioned that the prices are reasonable and typically include insurance.

Travelers have suggested doing a thorough check of the rental car upon pickup, including taking videos or photos of the vehicle to document its condition. This is a common practice recommended to avoid disputes about any damages that might be discovered when returning the car.

According to forum posts, travelers seeking the iconic Santorini view prefer staying in areas like Fira, Oia, or Firostefani, known for their caldera views. However, accommodations in these areas might be expensive and crowded, particularly during peak tourist seasons.

For those prioritizing beaches and a more relaxed atmosphere, some travelers suggested staying in Kamari or Perissa. These locations offer more budget-friendly accommodation options and are described as having a laid-back environment with easier access to beaches.

Some users have recommended specific hotels like Antonias in Fira for its proximity to transportation hubs, allowing easy movement across the island. For a mid-range budget, Kamari was mentioned for its reasonable hotel rates, and Firostefani was highlighted for its quieter setting yet close proximity to Fira's attractions.

Travelers have also emphasized the importance of considering the location's accessibility to local restaurants, transport, and major sights when choosing accommodation. Some posts have pointed out that staying in less touristy areas might offer a more authentic and serene experience.

According to forum posts, travelers can often purchase ferry tickets on the day of travel, especially during less busy seasons like September. However, for busier routes or during high season, booking in advance may be necessary to ensure availability.

Some travelers have shared that ferry routes in Greece can vary, with options like high-speed ferries or conventional ones that offer different experiences and speeds. High-speed ferries are faster but more expensive, while conventional ferries offer a slower, potentially more scenic journey. Depending on the route, ferries may connect directly to major ports or involve transfers, impacting travel time and convenience.

Travelers have noted that experiencing Greece by ferry allows for seeing diverse landscapes and exploring multiple islands. The journey itself, particularly on routes that pass through scenic areas like the Caldera in Santorini, is often highlighted as a highlight of the trip. However, ferry travel can also be long and sometimes delayed, so planning for extra travel time is advised.

For those seeking less touristy experiences, forum users suggest smaller, lesser-known islands that can be reached by ferry but may require more complex travel arrangements. These islands often provide a more authentic and quiet experience compared to popular tourist destinations.
