Hi Neil!
Thank you for bringing your question to the Disney Parks Moms Panel. On a recent visit I actually had this exact itinerary, staying at
Disneyland Hotel and enjoying a character breakfast at
Storytellers Cafe, and let me tell you it's a great way to start the day!
To limit unnecessary traffic and Guests cutting through
Disney's Grand Californian Hotel & Spa to get to
Disney California Adventure Park, Cast Members do restrict folks entering into the Resort hotel. As you have a
Dining Reservation though, you absolutely have a reason to be there and you shouldn't have any issue at all! When you approach the
main gate entrance off of Disneyland Drive, there will be a Cast Member asking those approaching if they are staying at the Resort hotel . You can let them know that you have a Dining Reservation for breakfast at Storytellers Cafe. I usually have either my
Disneyland Mobile App open or the email with the reservation confirmation just to simplify the process.
I hope this helps in planning your upcoming visit to
The Happiest Place on Earth! Please come back if we can be of help in any other way.
