What are some of the things you'd do?
I'd have so many things to see after missing almost 2/3 of Disneyland history(born in 1989), but the #1 thing on my list would be to see Walt in person.
-Go back to 1955 and explore Mainstreet's old shops.
-Everything in old Tomorrowland, boo new Tomorrowland.
-Go see 1950s Frontierland where most of it hasn't become yesterland remnants yet.
-See Bear Country
-Walk through the old parking lot to the Disneyland entrance.
