Hi Natalia!
I completely understand wanting to have enough days to experience all of the magic that the
Walt Disney World Resort has to offer! If your tickets were purchased after 2005, have at least one admission day remaining, and it is within 14 days of the first use of the tickets, you can
modify or upgrade your tickets! This means that you can add days or add the Park Hopper Option or the Park Hopper Plus Option to tickets that didn't already include those options. You can even upgrade tickets to
Annual Passes! Unfortunately, you can't downgrade a ticket to a type of ticket with fewer entitlements, so since your current ticket includes the Park Hopper and the Water Park Fun & More Options, your additional day would need to include the Park Hopper Plus Option.
Since you have used some of the days on your tickets, ticket upgrades have to be made in person, but there are a few different locations that you can visit to do so! You can upgrade tickets at any theme park ticket window or any
Guest Relations location, and if you are staying at a
Walt Disney World Resort Hotel, the
Lobby Concierge may also be able to upgrade your tickets for you!
Have a Great Big Beautiful Tomorrow!
