Hi Alvaro, welcome to planDisney!
Great decision on wanting to upgrade your tickets to a park hopper! I'm a huge fan of the park hopper tickets as they give you so much flexibility and control of your day! To upgrade your
standard one park per day theme park ticket to a park hopper ticket, you can either visit the
Disneyland Resort Main Entrance Ticket Booths or call the
Disneyland Resort Ticket Line at 714-781-4636. The Cast Members are great and can certainly help!
Also, as you move forward to upgrade your tickets, I highly recommend you consider adding the
Disney Genie+ service to your tickets if you haven't already. Genie+ is amazing as it allows you to skip the standby lines for most attractions and use the
Lightning Lane entrances! Lightning Lane entrances have been setup throughout the parks. They give you quicker entry to certain attractions usually resulting in less time spent waiting in line. Another amazing perk with Genie+ is that you also get unlimited
Disney PhotoPass Digital Downloads. Amazing right?
I hope you have the most magical time, and if you have any other questions at all, please visit us again!
See ya real soon!
Jin
