since the airline, via their voucher, paid for the room, per Marriotts T&Cs I see no problem here.............. you might have chosen the hotel, but other then that you were along for the (free) ride!
[QUOTE=ordflyboy;18737891]I recently misconnected on an international flight and had to spend the night in a hotel and connect the following day. In this particular case, it was Zurich and I chose the Zurich Marriott Hotel (at which I made a reservation).
Two weeks later I noticed that I did not receive credit for the night's stay nor did I receive the 500 bonus points for my Platinum arrival gift. ]
