No. You can only get to disney springs by boat from port orleans
You cannot go from Port Orleans Riverside to Epcot by boat.
Nope. The boat goes to French Quarter and Disney Springs. The buses go to each park. I'd recommend staying at Carribean Beach. They have the skyliner which has faster access to Epcot and Hollywood Studios with buses to each park as well
The only transportation to any park from Port Orleans Riverside was bus but at least most of the parks seem to have closer spots for Riverside and there was hardly ever a wait. I was surprised how fast we got there and back compared to my in-laws who stayed at Caribbean.
