I’m sorry the trip was postponed. For a first-time trip it should be the absolute best and doing it for Disney World’s 50th Anniversary will be even more special! If you need help with trip planning, our friends at Off to Neverland Travel do a great job. Our resident agent, @Chelle, is fantasmic.
I digress! A really fun activity would be to celebrate “This Day in Disney History” for each day of the week. Use this website to look up the history of Disney and do something themed in that way. For example, May 18th in 2015 Pixar’s newest animated film Inside Out premiered at the 2015 Cannes Film Festival.
