First choose the number of days you want on a Magic Your Way Base Ticket, which allows you to enter one theme park each day. Then you can 'add-on' which options you may want to add, paying for only those features you want.
There are four add-on purchases for the Magic Your Way Base ticket
Magic Your Way Ticket with Park Hopper Option - Adding this allows you come and go as you please through all four Disney theme parks on the same day or every day of your pass.
Magic Your Way Ticket with Water Park Fun & More - This provides additional admission to Disney's Blizzard Beach Water Park, Disney's Typhoon LagoonWater Park, DisneyQuest, Disney's Oak Trail Golf Course and Disney's Wide World of Sports Complex. You get a set number of visits to these additional attractions, depending on the length of the ticket you purchase.
Magic Your Way Premium Ticket - This ticket combines the benefits of both options above.
No Expiration - Magic Your Way tickets expire 14 days after their first use. Choosing the No Expiration option means that unused days never expire.
