I am thinking of 3 nights at Aria. The first on a myVegas reward, and the next 2 on a Hotels.com reward. Basically with hotels.com they give you a certain amount per night. If the room cost less, then you lose the difference. So I would have enough for a Strip View. I would like to have my myVegas room be in the same room as the next 2 nights. How can I get that handled? Will they charge me a ton or a modest upgrade fee? Is a $20 sandwich the way to go?
