Hi Nicole!
Several panelists recently answered a question about a
first time visit.
I recommend ordering a
free planning DVD. I also recommend buying the tour book "The Complete Guide to Walt Disney World" by Julie and Mike Neal. It has won 8 national awards and is full of color photos. It is a great book for first time visitors.
I think your child will enjoy any hotel and any of the theme parks at Walt Disney World, so I would plan on staying somewhere and doing those things that most interest you and your husband. If you think you will be spending most of your time in the Magic Kingdom then I recommend staying in a monorail resort or at the Wilderness Lodge to allow you to return to your hotel quickly to take a nap, rest, etc.. Likewise, if you will be spending most of your time in Epcot or Disney's Hollywood Studios, then I recommend staying at an Epcot resort located on Crescent Lake: Boardwalk, Beach and Yacht Club Resorts, Walt Disney World Swan, or Walt Disney World Dolphin. Another option is to have a car so that you can easily get from wherever you are to your hotel quickly.
A few more pointers based on my experience of bringing young children to the parks: slow down and enjoy the experience of visiting with a young child instead of running from attraction to attraction; take your own stroller because your child will be familiar with it; consider a character meal, but don't rush character interactions until you see how your child responds; do those things that your child finds most interesting, which could be playing at the resort hotel. The most important thing of all is to just have fun!
Write back if you have any more questions!
