As our wedding guests, you can ask to take advantage of pre-arrival savings on any Disney Theme park that includes a Park Hopper option.

You can start by requesting your free magic band in a color of your choosing, free of charge to be shipped directly to your home. These bands are used as your room key, parking pass, park ticket, fast pass etc. - it is recommended that these be ordered at least 1 month before your departure.
No worries you can sign up on line and just wait to be given a plain grey band when you check in, at which time it will be linked to the account you set up. Check out Fast passes for your favorite rides and get Dining reservations at Hotels and Parks. These book up well in advance so it is recommend that you look for those now. Dining selections can be canceled up to 24hr prior, after which you will be charged $10 per person for no-shows.
Or skip all of these steps and just bring your happy shoes.
