There are 21 1BR villas. 16 are located in Buildings 11/12 - the Live Oak Lodge where the front desk is located. The other 5 are situated under a GV in buildings 16,18,19, 28 and 30.
The villas in the lodge have either a marsh view or island view. Those in 16, 19, 28 and 30 have island views and building 18 villas have a marsh view. I'd request a view rather than a specific room though.
There are no ground level villas at the resort (due to building code flood restrictions). There is a parking garage under the lodge and elevators to the upper floors. The first floor villas in the other buildings have 12 steps up to the front door, but no underneath parking or elevators.
