We just stayed at CBR in a water view pirate room. We were in Bldg 35 and could see the high Epcot fireworks from our window.
My ds(5) LOVED the pirate themed rooms, but we won't do it again. You pay a lot to have one, but are really far from all the "stuff." We started driving over to Port Royale to eat and use the pool, because the walk got old. I usually stay deluxe and would rather be closer to the restaurants and amenities. It was cute though. Musty with mildewy curtains, but cute.
Oh yeah, and I don't have a bad back, but the bed killed me. I was so glad my dh who does have a bad back wasn't on this trip, because he would've been hurting for sure.
