I like to linger in the Epcot countries! I had been to WDW with my family several times, and we all like Epcot, but it wasn't until my first solo trip (my second is planned for end of May!) that I explored Morocco, found the terracotta warriors in China, and more.
I also like to check out the other resorts -- I went over to Grand Floridian last time and this time I think I'll take a trip over to the Polynesian, Wilderness, and/or Contemporary!
Have a great time!
