The hotel grounds are laid out in such a way that you can walk, take a boat (abra) or ride a buggy when moving around the resort. The warmer it is, the longer the wait for buggies and boats!
Only if you are not staying in the main Al Qasr hotel.
If you are staying in the Summerhouses or Villas, you will need the Abra or buggy service. Both services are a super way to get around and see the whole of Madinat Jumeirah
No boats run on the 'canals' and can be used to move round the complex but you can walk or take buggies as well. any transportation will only take you to near the hotel entrance. After that it is walking and a lift.
