I just checked on Cozumelinsider and then parks and the website says they are looking to open the end of February.

"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover."
That is a bummer! I was really looking forward to going. We are sailing on Celebrity Zenith and are due to be there on 2/22. Maybe maybe it will be open by then. It looks like a wonderful place to take my daughter.
Thanks for the info!
