In no particular order:
Test Track - I do not get it and I think it's even worse after the refurb. I don't want to spend forever designing a car. And even if I do the single rider line, the ride is so meh. What on earth is the big deal about driving 60mph for a couple of seconds?
Toy Story Midway Mania - Why do people wait hours for this ride? Don't get me wrong - it's cute and all, but not more than a 20-30 minute wait worth of cute.
Mickey Bar - It's an Eskimo Pie in the shape of Mickey. I love Eskimo Pies, but I can get a box of them for slightly more than I would pay for one Mickey Bar. Just not a good value for me, especially since there is nothing special about them since I can have an Eskimo Pie anytime I feel like driving to the grocery store (on I35 where I will go over 60 mph for more than a few seconds Test Track).
Port Orleans French Quarter - It looks like the Mardi Gras section of
Walmart vomited all over a cheap motel.
Grand Floridian - Sure it's beautiful, but there are plenty of other resorts that are equally as beautiful (Beach Club, Yacht Club) and many resorts that are much better themed (Polynesian, Wilderness Lodge). If I'm going to stay at a deluxe resort, Grand Floridian would likely be my next-to-last choice.
Disney Dining Plan - Unless you are eating the most expensive thing on the menu at some of the most expensive restaurants, you are spending more for the dining plan than you would to just pay out of pocket. I also don't get the "but it's all paid for ahead of time" argument. So what? You're still spending that money. At least without the dining plan, I know I will be spending exactly what my food costs and not trying to figure out if snack is a good value or deciding I should buy some meal I don't want just to justify the cost of the dining plan. And don't get me started on the idea of using two credits for signature dining.
