1) Explore Your Resort
The one you are staying at or a different one. I always like to spend extra time checking out my resort when it rains. It feels like home. When it rains for a long period of time, I usually go and check out another resort too. Disney's Grand Floridian and Polynesian are some of my favorites to look around, especially because I don't think I will ever get to stay there on my budget at this point.
2) Have a Fun Restaurant Experience
There is no rush when it rains. Go to a new restaurant and explore different options. Go to a character or fine dining experience. Enjoying a dinner show might be fun too. Make the most of it — always order dessert!
3) Do the Indoor Stuff
Ride the indoor rides and take advantage of shorter lines. Some people even line up for the outdoor rides that usually have a long wait, but are temporarily closed because of the rain. Rides like Seven Dwarfs Mine Train and Avatar Flight of Passage would be great to wait for, considering that those rides are always packed. Be sure to have your poncho though, if you do that! Meet some characters, too: Talking Mickey, Tinker Bell, Princesses — so many to choose from!
