Welcome to planDisney Katherine!
Great job on making your
Dining Reservations! This is always my favorite part of planning with so many wonderful restaurants to choose from. My family and I recently had dinner at
Boma - Flavors of Africa at Disney's Animal Kingdom Lodge. If you are looking for an amazing buffet, Boma is the place to go!
If you need to change your dining party size, you can do so by logging into your
My Disney Experience account. Under My Plans, you will see your daily plans complete with any Dining Reservations you have booked. Choose Modify Reservation to change your party size. Hopefully you can add that additional guest.
In the event you cannot add on another guest, leave your reservation as-is. Arrive to the restaurant a few minutes early and let them know you have one additional guest. It should not be a problem, but you may have to wait a few extra minutes for a table. If you start adding 2, 3, or more to a reservation, they may not be able to accommodate you as there may not be a table big enough for your party size.
A little tip for you....Dining Reservations are always changing on the booking site. Guests add and cancel and change plans a LOT! If you don't see what you want, keep checking! I have gotten last minute reservations at popular locations like
'Ohana at Disney's Polynesian Village Resort and
Chef Mickey's at Disney's Contemporary Resort. You just never know!
Wishing you magical meals at Walt Disney World! Enjoy!
