Small Island Resorts

Hello

I am looking for a specific type of vacation/resort. Basically an island small enough that the whole island just has the resort on it. There’s plenty of examples of this in the Maldives, but for the Caribbean I’m only really aware of this type of resort in Belize (Ray Caye, Shaka Caye, etc.). Anywhere else in the Caribbean with similar setup? Any particular resorts you’d recommend?

We’ll be travelling from the West Coast of Canada (BC). We are also not divers, so that is not a requirement but we enjoy good snorkeling, kayaking, etc. I understand this will be a very laid-back type vacation. Also not necessarily looking for super luxury (over-water villa type stuff), though not opposed to some luxuries. A nice clean setup with the basic amenities (AC, pools, restaurant, bar, etc.) might be enough depending on the price.

Thanks!
