HW or Epcot

I think both EPCOT and DHS are more than one day parks. World Showcase is a full day if you want to explore the countries, and DHS has a bunch of fun shows, so I think it really depends on what you like to do. If you want a full day in WS, I would go to EPCOT and do the other “areas” of the park on the half day, and if you want to do everything at DHS, I would do that as the half day, and try to get one side of the park accomplished (maybe ToT, Rock 'n RollerCoaster, Beauty and the Beast, Fantasmic!, etc. for the half day, and then do Toy Story Land and Galaxy’s Edge during the full day.

Good thought, but we do not have park hoppers.
