With the FP, apparently you bypass the regular themed queue which has a talking Mr. Potato Head, among other things, I'm sure.
Now personally, I would love to see the regular queue with Mr. Potato Head, but not at the price of a 90 minute wait! No way. I will FP next week, miss Mr. Potato Head and hope that at some point in the future (like one of our January vacations), we will be able to take the regular line with no or little wait. I would ride standby at RD to see the whole thing, but we're on SWW character mission next week ...
