That sounds WONDERFUL! (No pun intended!)
Do they post character greeting schedules like the parks or do you just stumble upon the characters?
We just returned Friday from our best of 6 WDW trips - the highlight, as always, was DD's (now 7) time with Pluto - her favorite since her first trip at age 3.
We're definitely going on the Wonder in late Feb. (our Mardi Gras vacation) but it would have been a letdown for her if "her Pluto" wasn't there!
