TourRadar operates as a middle man for your bookings. They tend to charge you first for the whole amount, and latter contact the vendo and check availability. When it comes to communication with the vendors, you are left on your own. They monior the converstaion without interuptins or interference. If the deal goes south - the vendor is to blame! Tried to book a sailing trip where the original listed price was at $500. Had to wait for 4 days from the vendor to get back with news that I must pay extra $250 - due to a "highly demanded week". OK, not to fuss I agreed. only to be contacted again with info that now, if I still wann go must pay for an cabin upgrade @ $1500 p/p... Happily canceled this resevation with the wannabe pirate, however still had to wait for 2 weeks for my funds refund. Again, TourRadar newer interfered ?!
