I guess it depends on what you like to do and whether or not you will have your daughter with you...

I would personally suggest visiting the spa at the Grand Floridian... (Im dying for a massage hahaha)

But honestly, I think you can do something not totally our of the ordinary, but just make it special for yourselves AND your daughter... maybe a character meal you can all enjoy, or a nice dinner... we have a FANTASTIC dinner at Sanaa, the place is gorgeous, and if you get a window table you have the animals walking right past you.... so that kept Tatiana entertained
