Hi, Nancy! We can't have you waiting around all day for your husband to get out of his meetings, we need to set you up with some activities!
You are staying at a great resort. The grounds and landscaping are beautiful at Port Orleans Riverside. Take time for a morning stroll to see how pretty everything is. You might even take the walkway down to Port Orleans French Quarter. Snack on some Beignets from their bakery!
From either of the Port Orleans resorts, you can hop on a boat to
Downtown Disney. There are some great shops and restaurants here. You can spend several hours with all there is to do! (You can even catch a movie if the weather isn't so great!)
Another option is to take a bus from your resort to the Magic Kingdom. From this stop, you can hop on the Resort Monorail which stops at 3 Deluxe Resorts: Contemporary, Polynesian, and Grand Floridian. Hop off at each resort to see these awesome properties! Each have amazing lobbies, shops, and restaurants. You might grab a beverage and relax on one of the swings on the Polynesian Beach. From here, take the walkway to Grand Floridian. Peek in at the Wedding Chapel along the way and don't miss the fabulous lobby of the Grand Floridian. From the Grand Floridian, take the monorail back to Magic Kingdom where you can catch a bus back to Port Orleans.
These are just a few ideas. Once you are at Disney, you will find plenty of activities to keep busy (just keep a few things to share with your husband when he's done working!) Have a great time.
