Hey there, Sharon, and welcome to planDisney! I'm thrilled to hear you have a trip coming up in September - that will be such a fun time to visit the Happiest Place on Earth, but more on that below.
As for your
theme park reservations, you may have already discovered this since you submitted your question, but they are made available about 120 days out from the current date. As of the time I'm writing this response, the
Theme Park Reservation Availability Calendar goes out through September 19! Depending on how long you're visiting, this might cover all of the days of your trip since it looks like you indicated your arrival date is September 17, but even if you're staying longer, you can still make the reservations for those first couple of days.
My family and I love staying at the
Disneyland Hotel! You made a good pick with that one. Don't forget to take advantage of your
Early Entry mornings each day of your visit! You'll be able to sneak in a couple of rides before the parks open to other guests.
When you visit, it will likely be
Halloween time at the Disneyland Resort. They haven't announced the official start date for this season on the
Disney Parks Blog, yet, but in previous years it has kicked off the first weekend in September. I love this time of year at the Happiest Place on Earth! My son is a huge Jack Skellington fan, so we love riding
Haunted Mansion Holiday, there are fun Halloween-inspired snacks and treats, décor, and special parades and nighttime spectaculars as well. Again, keep an eye on the Disney Parks Blog for more info - I'd imagine more will be revealed soon!
Thank you again for your question, Sharon. You're going to have such a great time! Make sure to come back and see us here at planDisney if you think of any other follow-up questions. We'd love to help!
Have a Magical Day,
Greg
