I'm trying to plan a little get away with a friend to the Vegas strip. We're trying to be budget conscious. I am loyal to Marriott so my first choice hotel would be the Cosmopolitan. I'm a silver elite member and was wondering if they offer upgrades at this level? Also, is there a door from the bedroom to the bathroom? It was hard to tell from the picture of a City room. Any tips would be appreciated. Last time I went to Vegas, they were just building this hotel.
