My husband and I took our grandson down there last Feb and stayed at POFQ. Both my GS and me are early risers, so we dragged my husband out of bed every morning and made every single rope drop or else did an early morning character breakfast. We then took a break everyday, right after lunch. When the parks started getting crowded, we knew it was time to leave. Our GS loved the pool and even though he never takes a nap at home, took a nap every day after swimming. He'd start off playing quietly on the bed with his toys, but within a few minutes was asleep. His grandpa napped too.
While they were sleeping, I read on my Kindle. After they woke up, everyone was relaxed and ready to go to dinner and do more park time. It worked out well for us.
Heck, as an AP holder, I go to WDW 4-6 times a year and several of those trips are solo trips. Even on my solo trips I usually go back to the room, shower, get cooled off, read, and relax in the afternoons. That way I'm recharged for dinner and am not as exhausted at the end of the trip. At home, I work night shift and sleep in the afternoons, so need a rest in the afternoon, even if I don't go to sleep down there.
