It's really up to whether or not you enjoy splitting your stay up. I personally don't care that much for it, but have done so out of necessity a couple of times, and am doing it for spring break (two nights at Pop using some Orbitz rewards dollars, followed by seven nights at AKV rented from an owner in a one bedroom villa). The first two nights are just me and DD, so we won't unpack. We're just there to relax and sleep, and won't buy and drinks more than we will drink in the room, and no snacks also. Getting delivery of groceries the day we move over to AKV.
I like to have snacks in the room and drinks, so moving any extra would be a pain.
Honestly, if it were me, I'd save and either do the whole stay at Pop! I loved it there. The bus service was really good, the food court was great, room was fine & clean & quiet.
Or, I'd look at the Swan or Dolphin if you love the Epcot resort area (I do love that too!).
