I would suggest looking at a map of the resort and pick a building that suites your needs. We requested 38 because it was by the pool and bus stop east (i think it was east) but we were staying a week. Since your only staying for one night I''m not sure it matters to much.
We plan on spending most of saturday at the resort. We have a garden view room. We are huge fans of POFQ and CBR. It will be interesting to see how POR compares.
I second Marijil above me here, don't rule out Bob until you see him, he is one of the best. And the service at the River Roost Lounge is amazing. And I've enjoyed hearing Elliot play as well over at POFQ, sad to see him go.
