The Westin Hapuna hotel is a great resort for a family vacation. The hotel is located on the northern west part of the Big Island. The area itself is very remote, not habituated and fairly far away from anywhere. We had to travel everyday to eat outside but that was fine as we wanted to get out of the hotel and see things.
The room was comfortable, beds were fine but not great - turns out the local Queen size bed is smaller than the California standard. TV, fridge, hair dryer etc. were there. The toilet, bath tub and shower room was big and had two separate sinks which was great. There was also a nice small balcony.
Pools were awesome, there was an adult pool with a jacuzzi on the upper deck, and a kids pool in the lower deck. Since the hotel capacity was about %30 nothing was too crowded. The children had a lot of fun playing in the pool. There's an easy access path to the hotel's private beach which was really great. On the beach they have sea beds with parasols. There's a little bit of snorkeling on the right end of the beach where near the rocks, nothing fancy. There were much better snorkeling sites elsewhere.
Rooms were cleaned every 4 days, room service was great replacing towels and taking garbage bags.
