Hi Nicola! Welcome to planDisney!
I'm excited to hear you'll be visiting the Walt Disney World Resort this spring! Since you're staying at the Walt Disney World Dolphin Hotel, not only are you located in a fantastic area, but you'll also receive some perks during your stay. Guests staying at this hotel have access to
Early Theme Park Entry. This will allow you to enter the parks up to 30 minutes before the official park opening time. My family typically utilizes this extra time to ride a few attractions with minimal wait times. It's our favorite way to begin our park days!
When purchasing park tickets from the United Kingdom, the only option available is the
Disney Magic Ticket, which is offered for 7 or 14 days. To purchase a 3-day park ticket, you'll need to wait until you arrive in the United States. Once you land, you can access the US version of the Walt Disney World website and purchase the number of days you need. If you purchase your tickets while logged into your My Disney Experience account, they should automatically link to your account. If not, you can link them after you complete your purchase.
If you decide to purchase 3-day park tickets, you'll simply visit the park you want to each day of your trip. Park reservations are no longer required for date-based tickets, so you can show up to the Magic Kingdom or Animal Kingdom Theme Park on the day you desire to. Also, you'll only be steps away from EPCOT and Hollywood Studios since you are staying at the Walt Disney World Dolphin Hotel, so it might make sense to purchase a ticket that includes the Park Hopper Option. This way, you can end your day in either of these parks.
Nicola, I hope you have a wonderful time during your holiday!
Stop back and see us again at planDisney!
See ya real soon!
