Hi Ashley, and welcome to planDisney!
The more guests we have with us, the more fun we will have. I think that everyone needs to experience
Walt Disney World Resort with the ones they love for sure.
If the capacity of the guest room you chose is 5, it has to be five guests, especially if the plan is to occupy the same space. You will have seven occupants, so yes, that would mean two of your guests (not necessarily the children) would put you over the capacity. Have you considered reserving two rooms and requesting that the rooms be connected? That could be a viable option, depending on where you would like to enjoy your stay. The upside is that you would have two full bathrooms and at least four queen size beds for everyone to sleep in and enjoy. Another option could be staying at one of the villas, such as
Disney's Old Key West Resort in their 2 Bedroom Villa, which sleeps up to 9 guests. It comes with a fully equipped kitchen and two full bathrooms giving you plenty of room to hang out and fellowship.
We are here if you need additional assistance.
Have a magical time!
