Hi Jeremy, thanks for stopping by the Disney Parks Moms Panel with your question.
I am so glad you are planning to visit
Disney Springs while you are at Walt Disney World. Some of my very favorite restaurants are located here. More often than not, when I am at Walt Disney World, I find myself spending the evenings in this area enjoying all of the great meals, drinks and treats to be had here.
From
Disney's Port Orleans Resort - Riverside, there are a couple of transportation options to Disney Springs. While you wont be able to walk, you can take a scenic complimentary water taxi down the Sassagoula River to and from Disney Springs. This boat ride is especially wonderful in the evening and boasts stunning views when everything is all lit up. You will also be able to take the complimentary bus service to and from Disney Springs from your resort. Just in case it's exercise you're after, you may be interested in the 1.7 mile long
jogging trail that connects Disney's Port Orleans Resort - Riverside and Disney's Port Orleans Resort - French Quarter along the river that is available for you to enjoy.
I hope this helps! Enjoy your trip.
