1. If they liked or preferred Pop, why not stay there? The response that "well after that one dirty/disgusting room, I'm never staying there again" doesn't fly. I think every resort whether the Contemporary, POFQ, ASSports, resorts in other locations around the world, there's likely to be a problem in at least one room. Whether you're that unfortunate guest that gets that room or not, luck of the draw. But to say I'm never staying there again, I feel is a stretch. As for that room, absolutely gross for more than one reason - but why not have management walk them to another available room at Pop, have them look it over together and make sure it was more than acceptable? Why the move to another resort that god knows what kind of problem will arise there?
2. I can't imagine management just told them "if you want to move, this is where your staying and take it or leave it". They likely gave OP options and that's an option OP chose.
