Interesting you mention this, since we had a plumbing issue at Coronado, only back in September. We were in Ranchos 6B and it had been recently refurbished, as far as I know.
We'd just returned from an off-site day out, intending to dump our stuff, freshen up and head out to the parks for evening fun. However, the toilet developed a leak whilst flushing, spreading it's delightful contents all over the bathroom floor. Fortunately, we didn't have much of our stuff in there.
Anyway, we quickly got in contact with the front desk, who sent a handyman to our room about ten minutes later to take a look. Shortly after that, the head of maintenance came along. He took one look at the situation and said that we couldn't stay in that room and that they'd have to move us and that front desk would be in contact shortly with the new room arrangements. So, we packed up our gear and the front desk called us about 20 minutes later with our new room details. They were moving us to a premium room in another part of the resort. They asked us if we wanted Bell Services to help us move our stuff, to which we said yes. We waited ages for the Bell Services guy to show up (I'd say about 45 minutes) and we were just about to contact the front desk again to say that we'd move our stuff ourselves since there was no sign of Bell Services when he showed up.
By the time we'd gotten to our new room and settled in, it was too late to go to the parks, so we had drinks in the Rix Sports Bar instead.
As for the inconvenience, WDW bumped us up to a nicer room in the Casitas block - much closer to El Centro which helped. We didn't get any monetary compensation per se though. You see, earlier in the trip, we'd kicked up a bit of a fuss due to some missing photos from our Memory Maker and as a result, they knocked $75 off our final bill. Since we got our pictures eventually, we accepted that the $75 discount was adequate for our room moving inconvenience. Perhaps we could have gotten more if we'd have kicked up more of a fuss, but hey.
