On my last trip a copule weeks ago, I stayed at Aria which I booked thru Mlife. It was an Aria offer of discounted room and $100 credit. When I checked in, I asked if I could get an upgrade, but no luck on a suite. However, they put my in a high floor with a city view instead of the standard room. When checking out, I went by the player's club to see if I could get anything comped, which was a negative. I asked about my $100 resort credit and they said since I was in a city view room that it didn't come with a credit. I was in a rush to get the airport so I didn't stay to argue, etc. I was curious if this is typical if you book an Mlife offer, can an upgrade at the front desk throw that offer out?
