Hi there Ken,
Welcome to planDisney and thank you for your question! You're well on your way to planning your next trip to the Happiest Place on Earth - it'll be here before you know it!
It sounds like you're planning on arriving in the later afternoon of day 1, which will also be check-in day for your stay at the
Disneyland Hotel, and would like to settle in that evening. My family and I typically do this as well and we will grab dinner at the
Downtown Disney District on our arrival night.
Then you'd like the next day to be when you first visit the parks with your 2-day
theme park tickets. Finally, on that third morning, you're planning to check out of your hotel but would like to use the second day of your 2-day tickets. If that all sounds correct then - yep! You can definitely plan a trip that way.
To visit the parks of the Disneyland Resort, you need both valid theme park tickets (which it sounds like you already have with your 2-day tickets) and also
theme park reservations for each day you plan to visit. If you haven't already made those, or if you'd just like to confirm when you set them, you can check the
My Plans hub on the Disneyland Resort website. I've found it to be the most convenient place to make or manage all the different reservations you might want during a trip to the Disneyland Resort.
Thanks again for your question, Ken! I hope you have a wonderful visit to the Happiest Place on Earth.
Have a Magical Day,
Greg
