Kim,
I am a huge Coronado Springs fan. I have stayed there many times, both for work and fun, and have loved it every time.
But even more than that, I love to try out other resorts. I love the different themes, different amenities, etc.
So while you may lose some elements that you liked about
Coronado Springs, you get new ones at Port Orleans, like the boat access to Downtown Disney.
BOTTOM LINE: Try
Port Orleans Riverside. It has some amenities that no other Moderate resort has to offer. While you may miss some particular elements of Coronado Springs, you may find new ones you love even more! And regardless of your experience, you will know what is your ultimate Moderate resort when you are done trying them all out!
Have a magical vacation!
