We are going in about 10 days ::sqqqquuueeeaaaaalllll:: so i'll be happy to look into this for all of you. I looked at the cabana as well, but was discouraged with the price. I think you get two chairs and the cabana...and I THINK (please don't quote me) that there is a lunch involved too. Apparently they also are reserved quite quickly as they have been unavailable for our cruise for quite some time.
It would be great if you could take some photos so we can see! I hope you have a fab time and can't wait to hear all about it!
