I used the vacation package planner on the Disney site, entered our dates, people in our party, and the amounts were $235 apart - $2521 vs $2755. Maybe the difference is I added Preferred Room for POP, but not for POFQ (didn't think preferred would be as important at POFQ as it is at POP).... That would reduce the difference.
Good idea to ask the boys, but I know they'd choose POP, if only because it's the only place they've stayed and they love it. But if you never try something else, you'll never know, right?
Thanks for the feedback, by the way!
EDIT: Oh I am an idiot. My POFQ package didn't have hoppers, so you're right, Janet, the difference is more like $460. Take off the Preferred at POP to compare apples to apples, and there's your $600. Sorry for the confusion. Looks like this is a moot question, not sure I can justify that big a difference, especially when no one's asking to upgrade.
