People in general have a lot of misconceptions about Walt Disney World and the Theme Parks that are part of it. I'm wondering if when you talk to people about Disney travel, you have a list of "Don'ts" that you include? I have a couple, but would love to hear yours!
My Walt Disney World Don't List
1) Don't assume you can "do it all" in one trip. You just can't, period.
2) Don't assume you don't need ADRs. Especially during busy seasons you really do need to get your dining reservations in order early if you want a leisurely sit down meal.
3) Don't get caught up in "getting you money's worth." Cost is what it is, but once you are there you really need to let go and just enjoy yourself. I'm not saying that you shouldn't budget, but worrying about the cost of things during your whole trip can really ruin the magic. This is one of the big reasons I'm a plan of using the dining plan.
4) Don't compare it to any other Disney Resort you have been to previously. Each and every Disney destination is unique, they may have similar themes in certain areas, but all need to be taken on their own merits.
