Hello Robert, and welcome back to planDisney! I love that you're a planner just like me, and you're definitely ahead of the game, let's get a plan in place for your theme park reservations!
You are correct that you can begin making your
theme park reservations 120 days in advance, which would be around mid-August. If you make your reservations right then, I don't anticipate you'll have any issues with booking your dates, especially since you have
Park Hopper tickets. I always use the calendar feature in my e-mail and my mobile phone to set a reminder of when that date is so you'll know to book your park reservations that day!
It sounds like you have your hotel taken care of which is fantastic, so I'd also set a reminder for yourself to make any
dining reservations up to 60 days in advance! Since you will be visiting during the Holiday season, which I think is one of the most magical times to visit, maybe you'll want to treat yourself to a special meal such as
Blue Bayou Restaurant at
Disneyland Park, or a
character dining experience for dinner at
Goofy's Kitchen at the
Disneyland Hotel!
I hope this information was helpful for you Robert, I'm sending you pixie dust and good vibes that you get your park reservations for your desired dates!
Have a magical day!
Melissa
