Hi Jennifer!
Welcome to the Disney Parks Moms Panel.
Yes, if there is availability at your chosen restaurants, you will be able to add your relatives to your dining reservations. I recommend you do this by calling (407) 939 3463, and have your dining confirmation numbers ready when you call. All dining reservations are open to everyone, whether or not all Guests are staying at a Disney Resort hotel, so even though you are staying at
Disney's Pop Century Resort, and your relatives are staying elsewhere, that is absolutely no problem. It's worth noting that if you are using your
Disney Deluxe Dining Plan to pay for any of your meals that day, you may only using the dining plan for anyone on your Disney Resort hotel reservation. Just mention to your server that you are using a dining plan, and your guests will be using another method to pay for their meals. If you are making new dining reservations, you can do this
online, or by using
My Disney Experience.
I wish you a magical day with your family at
Magic Kingdom Park!
Please come back and visit us if you have any further questions. We will be happy to help you plan your vacation to Walt Disney World.
Sue
