Hi Brenden, and welcome to planDisney!
Disney’s Port Orleans Resort - French Quarter was the very first resort my husband and I enjoyed a stay at (pre-children), so it will always hold a special place in my heart.
You can certainly visit the resort using your vehicle. I can not begin to tell you how many times we have visited Disney’s Port Orleans Resort - French Quarter, not just to enjoy a stay but to partake in the yummy dining options that are a favorite of my family, who have food allergies. So you are free to visit the grounds, take a few photos, grab a bite, or shop. When you arrive, just let the security cast member know why you are there, and they will let you know how to proceed, but be sure to have your ID handy.
If you have additional questions, we will be happy to help.
Have a magiacl expeirence!
Raquel
