Hi Ricky!
Welcome to
planDisney! Exciting to hear that you and your friends have a trip to the
Disneyland Resort coming up!
The Disneyland Resort limits the number of Park Hopper Tickets that are sold, and as this is a popular option, they do tend to sell out. If you do not see the Park Hopper Tickets
available for purchase at the Disneyland Resort website, it likely means they are sold out.
You are absolutely correct, to make a
Theme Park Reservation, you must first have a valid
Theme Park Ticket. You can however always check the current
Theme Park Reservation Availability anytime without needing a ticket.
With all that said, I completely understand the goal here is to have a magical time at the Disneyland Resort with your friends! While Theme Park Tickets are nonrefundable and nontransferable, they can always be upgraded. If you do decide to purchase a Standard Theme Park Ticket, you can visit the Disneyland Resort Main Entrance Ticket Booth to see if options are available to upgrade to a Park Hopper Ticket.
I truly hope you're able to enjoy all that the Disneyland Resort has to offer with your friends! If you have any more questions, swing by, we're here to help!
See ya real soon!
Jin
