We spent only one day in Bahamas flying from Miami and returning in the same day. The driver of the minivan that we hired for the day took us to this hotel and told us that we could use all facilities as if we were guests. We did! We used the pool, the beach, and only paid for a snack in the pool's bar.
Would you believe?
I don't know the conditions and prices, but if I had to sleep in Bahamas this should be my first option.
