Hold up, no park hopper? I tell everyone to definitely get the park hopper. You never know what type of mood you're going to be in each day or maybe you don't have a super structured vacation (except dining, that has to be structured, and again, is a good reason to get the hopper if you don't want to be in Hollywood Studios all day but you are eating there in the evening and seeing Fantasmic).
And maybe she just ate somewhere bad in EPCOT. I know some places are definitely better than others. I'm not a fan of the Mexican or French restaurants (and mind you, I do like Mexican food). The Canadian restaurant has really good steaks (at least from what I remember, now that it counts as 2 meals on the dining plan I haven't gone in a while) and The Rose and Crown has pretty good steaks (and other food of course) as well. Sure, the buffets everywhere are going to be pretty standard affair, but to call them awful? Nah, I'm not having that. And to not go to Liberty Tree Tavern? That's just blasphemy.
As for ponchos. I've been there many times, and honestly, why bother with a poncho? The article indicates she went there recently, so it's obviously hot and humid there. It only rains for short bursts at a time (at least usually that is how it goes) and then you are stuck with a poncho. I say, take advantage of this time. People are afraid of some rain so they all huddle for "safety." While they are doing this, go hit up some rides or since it is still hot out, just keep on going with your day (unless you happen to be the Wicked Witch, then you can stay inside, just hope you don't run into Regina).
And I take it she didn't stay on a Disney resort. If so, the whole parking thing wouldn't be an issue. But even so, $17 isn't a bad deal. Try going to an Eagles game, I think that's like $25 a game. A lot at Ocean City, NJ is like $25 in the summer (well, there you can go on side streets to hit up a meter or park far away enough and get free parking).
For the memorabilia, well yeah, anyone with common sense would know not to blow hundreds of dollars on it. Unless of course you want to buy something to put away as a gift or you start some sort of tradition (my mom gets a Christmas ball each year we go with the year custom written on it with some sort of design).
Really, I think everyone on here could write a better top 5 list on how to do something at WDW.
