On previous sailings we've gotten either a cabana or a beach bed in South Beach. However, when my husband was booking excursions, he accidentally got a beach bed on Chill Island instead of South Beach (much to my dismay.) For those that have been over there, what is the area like? Is there even a beach or is it all rocks? Also, do you get food and drinks delivered to you like the cabanas and beach beds on South Beach?
