Howdy Melanie! What a fabulous question!!
Speaking from experience, my husband and I dined at
Cinderella's Royal Table prior to having children and I think I enjoyed the experience more than some of the kiddos. It was truly magical! We sat at a table by the window and I truly felt like a princess.
More than likely, the number of tables with kiddos will greatly outnumber the number of tables with adults only but don't let that stop you from having a wonderful experience. We have dined at Cinderella's Royal Table several times since becoming parents and it is not uncommon to find tables with adults only.
Be sure to check out the menus to determine which would be best for you and think about crowd levels as well. If you enjoy a breakfast or late dinner, you might be able to enjoy the Magic Kingdom with a smaller crowd level before or after your meal...which will be a bonus!
Cinderella's Royal Table is one of those "must-do" dining experiences. It is truly a magical experience and I think you will love it. They do turn tables rather quickly due to the high number of reservations so it if you are hoping for a slow meal where you can sit for hours and enjoy the company of your hubby, this may not be the right choice. If however, you want a great meal with impeccable service, it's a fabulous option. Add in a little magic and pixie-dust and it will be a meal that you will remember for a lifetime!
Please let me know if you need any further details and have a magical day!
