Hi Heather!
My boys like to visit the
miniature golf courses on Disney property. There are two of them, and they are both really fun!
Another great thing to do in the evening is to visit
Downtown Disney. You don't need a ticket to go there and there is so much to do! Restaurants, shows, shopping, arcades, movie theater, etc. On a recent visit to Disney, it was raining all day, so we headed over to the Fork and Dine theaters at AMC. It was really neat to order dinner and eat all while watching a movie on the big screen!
Also, check at your resort for their weekly activities. They often have children's events planned for in the evenings. Crafts, movies, storytimes, and more!
I hope this helps! Have a great vacation and let me know if you have any other questions!
