Cosmos is at the far end of the beach, but they have a shuttle there and back for cliff dwellers if you want. They will watch your stuff. Most of the non-AI's are glad to have you - Sunbeach, Fun Holiday, Travellers (but their beach is really not great), Sunset on the Beach (the bartender is a sweetie!) - but it's at the end near Negril. Most charge for chairs. Buy a few drinks and you're good to go.

What are these containers from Walmart? They sound great!
