Anyone with cable can hardly have not noticed the absolute deluge of the same ad being repeated, repeated, repeated, on multiple channels by some hysterical siren ad nauseum demanding that we guess how many hotel rooms she's been laid in, err, hotel prices she's compared. Those of you tempted to try out this hotel booking service could do worse than to do a google on "trivago complaints" or similar. You'll easily find many horror stories that Trivago does not seem to have any interest in correcting (and this is after payments have been accepted). Admittedly, there is a smattering of positive messages, but these look suspiciously manufactured. Anyway, caveat emptor. Oh, and for those enquiring minds that just need to know the answer to how "many hotel prices have been compared" ... ... ... the answer is ZERO. They sub-contract the work.
