Hi there Mr Single, Accommodation seems to be a huge problem at the moment, The Marriott in my opinion is a great hotel, however try these hotels, I'd hate you to have to sleep in a strange car. (code 974)Four Seasons 4948888, Grand Regency 434 3333, InterContinental 484 4444, La Cigale 428 8888, Millennium 424 7777, Movenpick 496 6600, Sharq Village 425 6666, Sheraton 485 4444, The Ritz-Carlton 484 8000, those are all 5 star hotels in Doha, Four Star, Al Bustan Hotel 432 8888, Al Liwan 424 2888, Doha Seef 441 1442, Le Park 425 5555, Mercure Grand 446 2222, Movenpick 429 1111, Royal Qatar 424 9444, Ryges Plaza 438 5444.
