Greetings, Gwen!
Your sons have great taste! I adore both of those characters and would love to give them each a big hug, or maybe I'd have to settle with a high-five and a hand hold--they might both be a little hard to actually hug.
On my last vacation I happened to be looking for Wall-E items and found several adorable pin sets all over the
Walt Disney World Resort in places like
Disney's Pin Traders. If your boys are old enough, I definitely recommend introducing them to Disney Pin Trading and perhaps starting off their collections with a few Wreck-It Ralph or Wall-E pins.
Another fun idea to get them excited about your first Disney vacation would be to create a Wreck-It Ralph or Wall-E themed Disney Vacation Countdown. You could buy a cheap pair of small boots (like the one in the movie) and plant a seed to watch grow as you countdown or make a peppermint tree with branches for each day remaining. Just be careful for those double stripes!
Also, depending on when your vacation is, there is a new Wreck-It Ralph movie (Ralph Breaks the Internet) coming out this fall so you may find new experiences or merchandise associated with it. My fingers are crossed for you!
Have a magical vacation, Gwen, and please let us know if there is anything else we are able to assist you with.
Pixie Dust,
Lauren
