I remember that discussion and no one suggested the rooms would be ready "the next day", which would be impossible as all of the players' rooms were outfitted with special bigger-than-king-sized beds and the queen beds were taken out. Not to mention the players' lounges and fences that were set up. Plus the rooms are not getting daily housecleaning, so, in addition to replacing the furniture (and in some cases, taking massage tables and weight equipment out), they will need a deep cleaning. If took at least a week or more to outfit the resorts to accommodate the teams and WDW has given itself a little over a week to get YC back together for regular guests (last "regular season" games are August 14, YC opens August 24). That timeline has been in place for quite some time now and I would think WDW would know how long it's going to take for them to turn the resort over for regular guests. There were many videos posted of the work that was put into the GF to get it ready. It gives a good sense of what will need to happen once the players leave as well.
I just don't know where you get the impression these players are trashing hotel rooms? They travel all over the country and stay in hotels most of the year and there have been zero reports of any of these players ever damaging hotel rooms. They also aren't allowed to have any guests in their rooms at this point so there are no "parties" going on in the rooms.
