I see the birthday buttons have been mentioned, I just wanted to note that they say it does not have to actually be your bday, just that you are *celebrating* your birthday. We go every year to celebrate my and my ds bday, but sometimes the trip does not fall on the actual bday.
Also, they have a ton of different pins, on CM gave us some for a family reunion with the Incredibles on them because we had our matching Incredibles shirts on.
If you time it right, you can get on the launch from fort wilderness back to MK during Wishes, and get to see it from the water - HOW AMAZING - even better than from CG. We had one of the best magical evenings at FW, pony ride, hoop-de-doo, then a wagon ride, then the launch back. A nice break from the park and still wonderful.
This is one of those "not so secrets" but there is a lot of things you can do at the barbershop at the beginning of main street. Baby's 1st haircut is the big one, but they will also do up a kids hair with sparkles and color - not sure of the price.
And this isn't an "official" thing, but we bought my son the mickeys hands one year, and all day long cm and characters came up to slap him five, and during the parade almost every character made a point to come over to him to do the same. It was crazy! Now we bring them back with us every year, it was a great investment LOL
