For our 4 yo these are the Epcot highlights:
Living Seas - we spend forever here. Our 4 yo loves the manatees and the fish. Our 1 yo loves to ride the escalator
.
Land - Food Rocks is fun, haven't done boat ride with the 4 yo yet (might be boring?).
Maelstrom - or the boat ride with the mischief guys (as our 4 yo calls the trolls).
Rio del Tiempo - or the volcano ride as our 4 yo calls it (beacuse of the 'volcano' in the background of the Mexico pavillion).
Illuminations
Tapestry of Dream Parade (ends at the end of Feb?)
The model trains next to Germany.
Kidcot Stations and those @#$% masks. I really hate those masks (and the time it takes to make them) but our DD likes making them.
Other things that weren't hits.........
O' Canada movie - 4 yo had enough about 3/4 of the way through.
American Adventure - great show, but kids get bored.......but sometime fall asleep
(although sometimes I even find myself nodding of on a long, hot day
).
Other things we will do next trip...........
Journey Into Your Imagination - now that it is back to Figment (was closed for rehab on our last trip).
Test Track - might try this one out on our DD - she will be 4.5 on our next trip and is somewhat adventurous.
Cranium Command - a lot of funny action, but a 4 yo might not 'get it'.
