These are the 1 Day Ticket Options:
With the Magic Your Way Disney World tickets, you first choose the number of days you want on a base ticket, which allows you to enter one theme park each day. Then decide which option you want to add to your ticket, paying only for those features you want, such as the ability to visit multiple Disney theme parks each day (Park Hopping) or to visit water parks, or other exciting venues (Park Hopper Plus Option).
The “per day” cost of tickets decreases if you purchase multi-Days. The most significant cost break occurs when you purchase a 4-Day or higher Disney World ticket. All Disney tickets expire 14 days after first use.
