This is info from my planner below... But there is also AAA discount.
Your guests can call the Wedding Ticket line at 407-939-7693.* They should have the wedding name and date on them so the agent can pull the information quicker.* The discount usually ends up being about $20-$30.

The discount is only good on a Park Hopper ticket, which adds $35-$55 to the base price of tickets, so it's only helpful if you actually need a ticket that allows you to hop between different parks on the same day.
