POR is very quiet, and very serene. It's almost a polar opposite to the parks. Riverside has a great Southern charm about it that isn't replicated anywhere else on property. Take a slow walk around, and maybe walk along the river down to FQ to see how they do things.
Yeeha Bob plays in the lounge, and he's a hoot! If you have time one night, definitely go see him. There's also the boat to DS, so that's really easy to get to.
Riverside has a great food court, FQ has some really good beignets. Walk back from FQ to Riverside with a box of 6, and take it all in. Just don't get powdered sugar all over yourself.
The doors are all on the outside, like a motel, but it's not a detraction. All the moderates work like that.
Flipside, Boatwrights, the Riverside TS restaurant is very hit or miss. Some people love it, some people hate it. But if you don't want to gamble with that, as said before, take the boat to DS. The buses are also hit or miss. Some people get lucky and get on their bus in 5 minutes, other people talk about seeing 3 buses to AK, 2 to Epcot and 2 to HS before that bus to MK ever shows up.
Regardless, I love it, there, and if it weren't for fighting traffic at 4 am to make some races, that would've been our hotel our upcoming trip.
