Swing by walmart and get a cheap 8 or so inch fan. They are small enough to fit into luggage, not heavy and because they are cheap they are loud. I also need one to sleep. I need the air blowing in my face, the sound isn't enough... If it is there is an app at the play store that is called Relax and Sleep. I sometimes use this plus the fan. I have this one and it is great....
The resorts do have a limited supply, so you can ask -- we asked for and got one last trip. Of course, we also brought a small one in our luggage. DH can't sleep without one, so better safe than sorry.
