We stay at Amsterdam Manor every year and never do the AI option there because we love going out at night to various restaurants and bars. We stay for 2+ weeks so eating and drinking out can get expensive. Amsterdam Manor's rooms come with a full kitchen or kitchenette so we usually do breakfast "in" and buy alot of our drinks at the main grocery stores (we pack a soft sided cooler and take that to the beach with us.) Of course, we also buy drinks at the beach bar during happy hour (2 for 1) and also order lunch from the beach bar on occasion, too.
There are a couple of restaurants you can walk to in the area (besides Mango's and Passions at Amsterdam Manor). But the majority of the restaurants are downtown (10 minutes away) or in the high rise hotel area (5 minutes away.) You can take the bus (which stops right in front of Amsterdam Manor and is safe and cheap), a taxi, or rent a car.
On the flip side, we have friends from England who stay at Amsterdam Manor and they always do AI there and prefer it since they don't like messing around with the money exchange, etc.
But it's really up to you as far as your personal preferences and how you'd like to spend your vacation.
