Hi Elie! Welcome to planDisney! Thanks so much for sending us your question!
How exciting that you're planning a visit to The Happiest Place on Earth! Making
Advanced Dining Reservations is my favorite part of planning a vacation. You are correct that Advanced Dining Reservations can be made up to 60 days in advance of the date you wish to reserve. While the
World of Color Dessert Party would typically be reserved 60 days in advance, we haven't yet learned if the dessert party will be offered for the newest version,
World of Color Happiness!, which begins on May 16th. I'm hopeful that the dessert party will be an option for this new nighttime spectacular. While I don't know for sure, I suspect that reservations just aren't available yet. I'm sorry that you haven't been able to make the reservations you're wishing for. I recommend that you continue to check for availability in the event that they might open up.
While you're making plans for what to do and see, be sure to check out the
Guide to the 70th Anniversary at Disneyland Resort on Disney Parks Blog. There is so much to celebrate and the guide will give you details about all of the pixie-dusted offerings.
If you have more planning questions, please stop by planDisney again. We can't wait for you to be our guest, and we would love to help!
Wishing you magic,
Lisa
