I am the opposite of everyone who has responded so far, my family is not big fans of Epcot and we always make it a half day park.
In the past, we have gone right at RD and get done the only 3 things we enjoy there.... Soarin, TT and the kids like the Nemo ride and aquarium, then we head over on the monorail to MK for the rest of the day. This year we will head to Frozen Ever After first, Soarin and I'll take the little one to Nemo while my husband and older DD go to the single rider line for TT.
