2 - Can I add another person to my dining party?
You can typically call 407-WDW-DINE and they can try to add a person to the party for you. If you aren’t able to add the person that way, then you can also try showing up to the Disney World restaurant. There are no guarantees they will be able to get an additional person in, but we have never had issues with it. If you need to add more than 1 person, you may run into problems. It would be best to keep trying to get them added or look for a reservation that accommodates your entire party.
