Cosmo hands down. Here's the lick: Cosmo is a Marriot location, and they have price matching. So basically if you find a site that has a lower price, they match it AND take off 25%. So you book through Marriott, then go to a off brand website (has to be same room type, days, everything) and send them a claim. OR you could book the room you can afford (city suite) then do the $20 - $50handshake (depending on the room you want) at the front desk and ask for the SPECIFIC upgrade. I've heard people getting wraparounds (no Bellagio view) on non busy weekends fam...but even the 1 bedroom is popping if you taking a chick.
i might hit that lick fam. appreciate ya. but i got to book thru marriot first before they can match it? i can't just hit them up now and let them know i can get a better deal on so-and-so website?
