Oh, I have some other ones (man, I really AM a sinner!)
I ordered a kids menu at Columbia Harbour House for myself. (and it wasn't good! poor kids that have to survive on that mac and cheese!)
I bring snacks and water with me IN the parks, whenever I'm at Disney (DL, DLP and WDW)
At DL, on the Indy ride, I have climbed over the rope between the exit and entrance "walk". When you get off the ride, and walk the 10 miles, part of it goes next to the queue. Well, it was 2 minutes after midnight, so the ride was closed, and I climbed over the rope to go on the ride just that one more time, as the last person for that day!!!
ETA: at DLP, I lied to get in for the Lion King show. You need tickets to see that show (they are handed out for free, but you have to stand in line to get them, which I didn't do) OR you need to eat at the restaurant that is at the Videopolis theater.
I lied to the CM, I said my dad and borthers were waiting for us with food somewhere at a table of the restaurant. That's how my mom and I got in...
Also at DLP, at the Santa Fe hotel, I made friends with a CM at the "bagagerie" (where you drop off your luggage before checking in/ after checking out. He always puts the Disney Express tags on our suitcases, for free (which means our suitcases are being brought to the train station, and we don't have to return to the hotel, pick them up, and carry them ourselves to the train station)
I do bring him Belgian chocolates though, every time we go, and we also send him a Christmas card + present.
He also keeps his CM only pins for me. He's so nice!!
