In case you didn't see it on the blog, there's a new sale going on:

It's not as nice as the suite cabanas at Barefoot Beach, but they are nice. Here is a picture of my wife enjoying a Labadoozie in a Barefoot Beach cabana. The main difference is the crowds. Nellie's is very crowded, especially with kids. Not necessarily IN the cabanas, just enjoying the beach itself.
The cost is $495. I was able to get it on sale for 20% off.
