Hello Mao!
I can tell you are getting excited about your
Disneyland Resort vacation! I stayed at the
Disneyland Hotel with my son and his wife in November 2021, and we had an incredible vacation! I know that you will love the Disneyland Hotel!
The official
check-in for all Disneyland Resort hotels is 3:00 pm (Pacific Time--the time in California). To access the pool area and fitness center, you will need a room key to enter these areas. Your Disneyland Hotel Guest privileges start as soon as you pick up your room keys and last until 11:59 pm on your check-out day. You can check in as soon as you get to the Disneyland Hotel, even if it is before 3:00 pm, and while there is no guarantee that your room will be ready before 3:00 pm, sometimes it can be ready before 3:00 pm, according to my experience. Also, you can use the
Disneyland Mobile App to check in to your Disneyland Resort and receive a notification when your room is ready. My pro-tip is to pack your swim stuff, some dry clothes, and shower supplies in your carry-on luggage because there is a small changing room with a shower in the Disneyland Hotel pool area so you can swim while waiting to get into your room.
I hope that your Disneyland Resort vacation is magical in every way!
