Pedro,
Thanks for asking your question to planDisney!
Yes, if you plan to visit
EPCOT, or any of the other Walt Disney World theme parks for that matter, you would want not only to have a valid theme park ticket already purchased, but you also need to use the
Disney Park Pass System to make a Theme Park Reservation. These reservations are date-specific, as well as park-specific.
The good news is that I just took a look at the
Disney Park Pass Availability Calendar, and it appears that at this time EPCOT is available every day in March. Now that can change, so I encourage you to make that theme park reservation as soon as possible, so that you don't miss out on your planned adventures.
To make that reservation, just visit your
My Disney Experience Account and you should see a link to making theme park reservations. You can do this for just yourself, or for several members of your party all at the same time, it is completely up to you.
BONUS TIP
But what about park hopping? If you have a Park Hopper ticket, you can still hop to other parks, as long as they have available capacity. You simply need to call the
Park Hopper Hotline (that is not the official name, but I am trying to get that to stick!) at
(407) 560-5000. The recorded line can tell you the availability of space at the other parks before you head over. Capacity for hopping is not necessarily the same as the number of spots secured by a Theme Park Reservation, so even if a park you want to hop to had no Theme Park Reservations available, there likely can still be space for park hoppers to visit.
Please feel free to
write me back directly if you have any follow-up questions.
Have a Magical Vacation!
