I love Pop personally. The theming is great, the transportation is one of the best IMO, and the food court is a lot of fun. Don't get me wrong, Riverside and the French quarter is beautiful and probably my 3rd choice hotel, the swan/dolphin being my 2nd. However, in the end, I'd rather take my savings from getting a code discount and buy disney stuff I don't need.
I guess you need to figure out what you want to do with your money and where you want to spend it. No matter what, you can't go wrong. You may even want to hang on to your bucks and apply them to your next vacation....perhaps a bounce back offer......
Have fun no matter what you chose!
Edit: The first year we went to POP my kids were 2 and 5, from there, we have been to the Swan and Dolphin, Pop and all stars movies, the C. Beach Resort, and a few others. The one they like the best is Pop. That is their favorite. The Swan (my daughter has a thing for Swans) is their second. They are now 4 and 7 and are again looking forward to Pop.
