We stayed at the POP for 3 nights in October, and we loved it. Everything is cheerful, fresh, new, and clean, and the theming is a blast. We thought the food court was awesome for breakfast and late-night snacks (the only meals we were there for). We were very happy with the bus transportation.
There is also a gift shop, arcade, bar, and pool bar. Plus you can request a view that faces Epcot if you think you'll be at the resort during Illuminations!
We felt very safe with the level of security at POP and with the fact that there are always people around. It felt much safer than any of the off-site hotels we've stayed at for similar prices.
Our only complaint was the noise--next time we will bring a fan or white-noise machine and request a room at the end of a corridor away from elevators and stairwells.
For the price, POP is a GREAT deal. We are going back to WDW in a week and a half and will stay at the Dolphin, which we prefer for the location, the Heavenly Beds, and the quiet, but it is TRIPLE the price of POP. I doubt we will ever stay offsite on a budget trip again if we can get a discount code for POP!
