Wait until you stay at POR to decide. POR is our favorite hotel. The boat to downtown is really nice, we love the grounds, and we tend to swim more because the main pool is so nice (and the magic cookie bars in the food court are awesome). One other thing is if we stay for park closing and POR bus line is too long, we hop on POFQ bus, fill up our mugs there, and enjoy a leisurely walk back to our room on the beautiful path.
However, my son loves POP. Says it's more Disney-ish. He is 21 now. I really like POP and one of the main reasons is the food court, but the pool is usually crowded and in the summer months the water is really too warm. One of the best things we found this past summer at POP was the great bus transportation. We almost always waited less than 10 minutes in either direction. That was really nice!
We went to AoA to check it out this summer and it looks cool, but for us it is definately not worth the extra money. We thought the food court had a really strong fish smell from the poo boy sandwich that would bother me.
There are many I am sure who would disagree with me though about AoA.
