Hi Chaitali, thanks for visiting us again here at planDisney!
I'm so sorry to hear that you were unable to book a reservation for February 18, 2022.
Theme park reservation availability is fluid and constantly changing as Guests can change their reservations themselves from within their
Disneyland Resort account. Unfortunately, we do not have the Genie's cosmic power to restore your prior reservation once canceled. I truly wish we could! But all hope is not lost. I would recommend you continuously keep an eye on the
Theme Park Reservation Availability Calendar as a reservation may open up!
Also, I did notice that there is a reservation currently available for Park Hopper tickets on February 22, 2022. If you currently have a one-day per park ticket, you could potentially upgrade it to a Park Hopper ticket and secure that reservation. To upgrade tickets, you can visit any of the Disneyland Resort Main Entrance Ticket Booths, and the Cast Members there can help you out!
I'm going to cross my fingers and send all the magic within me your way in hopes of securing a reservation that works for you!
See ya real soon!
Jin
