Hmm..Orlando has a lot of stuff to do. Other than the obvious theme parks, there are nightly carnivals, plenty of attractions, and great food. There is the Ripley Believe It or Not museum, and the House of Blues. One of the most famous attractions that I loved was Arabian Nights-a great dinner show featuring arabian horses and stunts. The cirque de soleil is also a popular show. There's also the Dolly Parton dinner show...a cattle round up dinner show I believe. Gatorland is cool too...a zoo with wrestling and such of crocs and alligators. And CityWalk is great eating, plus little shops and some clubs. (Although you probably won't be going to clubs with your mom )

Oh, and the carnivals can be cool to check out-if your the daring type, right in the middle of Orlando there is a huge ball that you get into, and it slingshots you up into the sky. Plus all regular carnival rides, games, etc. You should have fun.
Have fun!!
