Hey Howdy Hey Katie and welcome to planDisney!
Disney's Port Orleans - French Quarter is such a fun resort with some amazing food options. I am happy to hear that you are thinking of adding a third to your reservation to enjoy the Magic of your vacation together! I will be happy to give you more information on how to get this done. Giddy up!
Depending on what you will need to add for your third member of your party will determine your plan of action. If they need to be put on the reservation and will be purchasing the same Theme Park Tickets as you and your husband, you can do this from your My Disney Experience account online. If you only needed to do part of the trip or different ticket options, your best bet would be to
call Disney and speak with a Cast Member about adding them to the reservation. Just know that a third adult in a room does come with an extra charge per night.
If you already have a trip booked and need to add a member to your party and will be visiting the same length of stay with the same park ticket needed, you can do this right from your My Disney Experience account. Once you log in, under the main page you should see your reservation. To the right you should see an option to "Modify/Change Reservation". You can click on that link and then update their information to add them to your party. If you have a reservation and are less than 30 days from your date of arrival, you can still get this done, you have to call Disney and speak with a Cast Member about making this change.
One location you should put on your "to-do list" is
Scat Cat's Club - Cafe or
Lounge. This is a super nice location and a great way to start your morning or end your evening. Regardless of time, beignets are always on the menu and are a huge draw for Guests all over the resort.
I hope this information helped get you pointed in the right direction so you can make the updates accordingly. If you have any further questions let us know, we are always happy to help!
To Infinity and Beyond,
Nick
