Hi Joe,
The Studio/Lockoff side is like a hotel room, except that it has the kitchenette with sink/microwave, small fridge, coffee maker, dishes. If you need more room, and are interested in the Marriott, you might want to rent a 1 bedroom unit, which has a bedroom, and a separate living/dining/kitchen area.
The location/floor of the Marriott villas are assigned when you check in. The floor and view you will get depends on the unit type you are renting -- Ocean Front, Ocean View, or Garden.
Joe -- here's another link that might help you to visualize the size of the unit a little bit better. When you get to the link below, click on "Floor Plans". The first one is for a 2 bedroom unit. The unit locks off, and the bedroom to the right as you are looking at the floor plan is the studio/lockoff.
