Hi Carol,
Great question! I hope this helps!
Magic Your Way is Disney's name for your park ticket. This ticket can be purchased for different amount of days and the more days you add, the cheaper the per day price. This base ticket allows you to enter one park on any given day and you can re-enter the same park unlimited times in the day. You can add options to the ticket to give you more flexibility in your touring.
Park Hopper option allows you to enter multiple parks in one day and only be charged one day's admission. This is great for short trips or guests who visit the Walt Disney World Resorts multiple times. First timers, guests with little ones or anyone who might need extra pixie dust, I recommend skipping this option and just visit one park a for the day.
You can also add a Water Parks Fun and More as well. This adds the options of the water parks, miniature golf or DisneyQuest to your ticket.
FastPass+ is a great feature available to any guest. This allows you to book up to three attractions, shows, character greeting or other fun events at one park for the day. You then return at the time you choose and go straight to the front of the line. Instead of waiting in line, you are riding another attraction, seeing a show, dining or sleeping late. Once you use your third FastPass+, you can grab another FastPass+ which is available from the kiosks. You can keep doing renewing this FastPass+ until you are done for the day or no more are available.
Wishing you a magical vacation!
