We were at POP last year during
free dining (we didn't use
DDP) and I'll tell you it was the most miserable experience of my life staying at POP. I will not go back again. The resort was full to the rafters.

Rude - unsupervised kids running up & down hallways after 10pm at night. Rude guests too lazy to use key cards, and the list goes on and on. The food court was so full that you had to be a table vulture in order to get a seat and pray that your food was still hot when you finally managed to get a seat. The busses were filled to capacity and usually you had to wait for a couple busses before you managed to even get standing room only on it & that was going to the parks. Also, we paid for preferred, but a preferred location is not what we got.
Because of this & many other issues, we switched to ASMu this past January & loved it!! No issues with the bus transportation (only shared one time), the resort was much quieter since it's so much smaller than POP & the food court was great. They had activities every day for the kids around the pool & the movies at night poolside were great, too.
Overall - I'd tell you to stay where you are instead of trying to switch to POP, but that's just my opinion.
