Castaway Cay cabana question

[jenpink]

I was able to book a cabana for our upcoming cruise. We will have extra room in the cabana and wondered if we could add people to the cabana after we get on board. I was thinking my teenage daughter may want to invite a few friends. Would this be possible if no adults from their staterooms were in the cabana? Thanks.

The set price you pay is for 6 people. You can add people for an additional amount of $50 per person for a maximum of 10. You can add them once you are on the ship.
