West End is a town on the N.W. part of the Island. This is where the majority of the dive ops and restaurants are. AI means all inclusive. Coco view and Fantasy Island are on the other side of the island. Basically you check in and stay within the resort. Everything is included in your price, diving-lodging-and food. I will assume they have back up generators but so do many of the resorts on the north side. Personal choice. I prefer the ability to eat at different places at night and maybe even a little bar hopping. You can't go wrong either way.
