The boats to DD drop off at the Marketplace, just outside RFC. Planet Hollywood is considered on the West Side - but it is the first thing you come to if you walk through PI. There is a "shuttle" boat from DD/Marketplace to the West Side, but it doesn't start until late afternoon (4 PM I think). As for the buses, yes, they stop at PO-FQ before going on to PO-R. So you're always the first one on and off. The boats to DD are just the opposite though. They pick up at PO-R first, then PO-FQ, so at peak times (starting around 4:30 - 5:00 PM) you could wait for a while before there's a boat to DD that has any room on it.
Our room was clean - obviously not new. The carpet and walls could stand to be replaced/painted. But mostly all we did in the room was sleep and get ready to leave, so it was totally fine.
I hope y'all have a great stay! I can't wait to go back!
