Hi Mark!
How exciting that you're heading straight to an exciting dinner reservation with Mickey Mouse himself on your arrival day! Staying at
Disney's Port Orleans Resort - Riverside, you're in a
great location to be able to exchange your PhotoPass+ voucher with ease!
Once you're checked in and settled at your resort, head on down to the dock and jump on a boat for an enjoyable ride down the Sassagoula River to
Downtown Disney. You'll find that there's a Disney's PhotoPass location here where you'll be able to get your PhotoPass+ processed. The PhotoPass retail location is in the Marketplace near Team Mickey. Once you're processed, you'll be ready to head on up to
Chef Mickey's for your fabulous dinner and photo opportunities with Mickey and all his pals!
If you have time, stroll around Downtown Disney taking in the sights and shopping. Plan to head out to the Bus Depot area by the time you reach 45-60 minutes from your reservation time. Simply jump on board a Disney Transportation bus headed to Disney's Contemporary Resort. Upon arrival, head through the Contemporary's lobby and up to escalators to Chef Mickey's on the fourth floor concourse level.
Thanks for visiting the Moms Panel with your great question Mark!

Wishing you a simply Magical time at Walt Disney World!
