Just wanted to vent. I have a 2 night offer from Aria in the standard room. I know sometimes you get an email with an offer to upgrade to a suite. I haven't been lucky enough to get one of these. So on my past 2 trips I was able to upgrade (once to corner suite strip view and once to crystal suite) and pay that fee when I arrived. That is all fine and dandy except the room comes with airport limo transfer that I never get to use since I stay at Cosmo after checking out of Aria. I want to take advantage of the limo PICKUP at the airport but you can't do that if you upgrade at check in. Grrrr. Of course I tried to book the upgrade in advance but that is a no go - would have to pay full price for the room. Wish they were like Cosmo who have no problem letting you pay for an upgrade when you book your basic offer.
