Hi Janis, welcome to planDisney!
Great choice on booking dining at the
Disneyland Resort Hotels! I am a huge fan of
Goofy's Kitchen at the
Disneyland Hotel. I highly recommend that dining experience if you have the opportunity! The food is great of course, but what makes this experience particularly special is Goofy and his Pals dancing around to fun upbeat music! But back to your main question, yes you can absolutely exit and reenter the parks at your convenience. One item to know, reentry is subject to theme park capacity. If a theme park has reached max capacity, reentry may be temporarily disabled until capacity returns. But looking at your arrival date, since it does not fall on any major holidays, I don’t think you'll need to worry about the parks reaching max capacity!
You're going to have the best time! In case you haven't heard yet, so many amazing experiences have returned to the Disneyland Resort! The traditional character meet and greets have returned, which means Mickey and all his Pals are ready to give out the best hugs and sign your autograph books. And many of the fantastic nighttime experiences are back as well!
The Main Street Electrical Parade,
Disneyland Forever fireworks,
World of Color, and my personal favorite,
Fantasmic! have all returned!
If you have any more questions, please visit us again!
See ya real soon!
