You will have the best time!
Here is my list of what I tell people going for the first time:
-No flip-flops allowed. When you check in at guest service, you will get a list of do's and don'ts. Heed them. Capris and clean sneakers and a nice blouse or Disney T-shirt is fine for lunch, something nicer is best for dinner.
-Order the Pirate Punch.
-Play a game called: sip your water. It's fun to see how fast the Evian people refill the glasses.
-Take the camera into the ladies' room.
-Take a larger handbag into the ladies' room (esp. if you are a scrapper).
-At the top of the lift, turn left walk two steps. The phone booth is from the Happiest Millionaire and the shopping cabinet is just to your left from there.
-Buy from the shopping cabinet and pay with a debit or charge card. Ask very sweetly to keep the Club 33 pen you signed your slip with.
-Tempting as it may be, don't steal the chargers with the Club 33 logo on it.
-Tip well. The servers sometimes have to put up with strange people sometimes.
