DeeP, I have had the same great experiences as you at the BWV. Always great. I have never had any issues with CMs there. We had one small problem with a door on the freezer in the refrig in a studio once, called mousekeeping and they were there to fix within 5 minutes. Put a new door on right then.
Dads Dream, how awful for you. Did you write to WDW to tell them about these experiences after? It certainly shouldn't matter that you had checked out at all.
And a general comment, I think it's important to remember that good and bad experiences have, and will, be had at every single resort at WDW. ALL of our bad experiences have been at OKW. They have run from a bad room, to a bad check-in to bad mousekeeping, to broken and dirty room.
