OP Ive been going back and forth had it been me what would I have done. Till now it was stick it to them and force them to live up to what was booked.
then I thought they could very well have the last laugh by when checking out going over the rooms with a very fine tooth comb (sort of like what happens in Europe when you return a rental car)and ding me for every little nothing, that theyd normally just pass off and theyd get their $$ that way, or by constantly coming up and saying other guests are complaining and you have to hold it down , etc etc
Id probably just find another place. But Im very surprised at Corp who really allowed this W to scam you, a very big
to Corp for allowing this W to do as it pleases and negate a contract it agreed to. Sure that W can change its T&Cs no problem with that but for anyone else or even you hence forth but not retroactive!
