Honestly, and take it for what it's worth... if coming to Orlando and WDW is a rare trip for you, I'd say going to these stores is a waste of time. You will more than likely be disappointed, and will lose valuable time. You'd be better off hitting the
Walmart, which has a HUGE selection of souvenirs and you can also get a gallon of milk, LOL.
We do hit a couple of the crappy souvenir stores like the "wizard," and the kids can usually find something they "need" for a few bucks, like a little moana purse or something.
