Hi Michelle,
Welcome to the Disney Parks Moms Panel! How nice to have you stop in and ask this question!
First, let me say how sorry I am to hear that you have not been able to make a reservation at
Cinderella's Royal Table. I have faced that disappointing reality in the past as well. I encourage you to keep trying. Last minute cancellations do happen.
Cinderella Castle is iconic. Guests can stroll through the corridor of the castle but there are no rooms open to the general public otherwise. In addition to continuing to check availability at Cinderella's Royal Table, I would suggest that you try making a reservation at
Bibbidi Bobbidi Boutique - Magic Kingdom. This boutique is located inside of the castle and is home to magical princess and knight transformations.
If you would like an alternative princess dining experience, try
Akershus Royal Banquet Hall in Epcot. The setting is lovely and the food is good. We have done dinner and breakfast. On our last visit, we did a pre-park opening breakfast reservation at 8:00 a.m. then got in the stand-by line for Frozen Ever After as soon as we finished breakfast. We did not have to wait more than 10 minutes to ride!
Michelle, I am sending pixie dust your way hoping you do get a reservation at Cinderella's Royal Table so that you can enjoy the inside of the castle. My girls love ascending the stairs and feeling like royalty when we dine there!
Magic, memories and Minnie Mouse hugs,
Donyell
