Hi Carol,
Our family vacationed at Port Orleans Riverside (POR) this past January. All of the moderate resorts (including POR) have exterior corridors. The doors to the rooms open out to an outdoor hallway.
In addition, the rooms do not have patios nor balconies. There are plenty of wonderful places to enjoy the outdoors at the resort though. You'll find meandering walkways with benches, a beautiful pool area, and outdoor tables near the food court.
I would check out pictures. First check out photos
here. For more examples, see www.AllEars.Net and look under Accommodations.
I love the moderate resorts. You'll get a lot of amenities for your vacation dollars.
Thanks for your question!
