I just thought of something that might make you feel better, if things aren't perfect ( I had a big disappointment my last trip) and was really angry at the time, but time passes, and if you love Disney it's hard to be angry long. That was an aside, I do tend to be long winded sometimes
Any way, back to making you feel better...I took my parents for their last trip to Disney, and many things went wrong, and I felt really bad, until they thanked me over and over for the trip. They talked about how much they enjoyed riding the different boats seeing the flowers, and walking around Epcot. I'm their age now, and I could miss magic kingdom, except seeing the new parts, as the crowds are really big. I much prefer a nice meal, and evening boat ride or just sitting at the resort talking to my parents. They have long since passed and I still remember our last time at Disney together. Just be sure to take lots of pictures of your Mom and Dad, what ever you are doing....Best luck to you.
