MotoCaribe oftens takes guests to cabanas to show them what they're like. We took some folks to Bora Bora recently and peeked at the Presidential Suite. Wow. Just Wow. A hedonists delight. EXTREMELY nice. The price was around RD$2500 for 4 hours I recall.
We were also told that many rent cabanas to throw regular parties, and the owners of the cabanas cater and sell alcohol for them.
Most have websites. i searched "bora bora santiago" and found this:
BORA BORA APARTA HOTEL
Cabanas aren't just for kanoodling with putas and having affairs.
