Yeah, tripadvisor is actually a good one. Also, sometimes: hotelscombined, trivago, trip, traveluro...
Btw. called 5 min back, and the same: Lower rate found and verified, upon short discussion - while put on hold - however finally "since recently, we do not do PMG over the phone... please fill the online form...". REALLY?! Is the second time since last Mon, and getting nervous.
If that is indeed the case, then the PMG is now dead entirely :-(
Anybody tried over the phone recently? It also may be solely the "local" team rejecting (advised to reject) on the phone and refering to the online form. I was calling the German Hilton hotline.
