Welcome back to the Disney Parks Moms Panel, Suzanna. Disneyland Resort hotels cater to families, large and small.
According to your previous question, it looks like you'll be staying at the
Grand Californian Hotel and Spa. The hotel rooms can accommodate up to 5 adults, while there are suites which can comfortably sleep up to 12 adults. I contacted the hotel and they do not have rollaway beds available. However, some rooms have daybeds.
The best way to ensure you have the proper room or suite to accommodate your travel party is to contact the hotel directly at (714) 635-2300 or (714) 300-7300. The Cast Members are happy to assist you so that you and your family will have an enjoyable stay.
I wish you a magical time during your upcoming trip to the Happiest Place on Earth. Please visit us on the Panel again if you have further questions.
Sending you Pixie Dusts,
Kiki
