I will be staying at the Aria in November. After making my reservation, I received an email offer to e-upgrade to a one bedroom suite for an additional $50 per night (if available). I typically ask at hotels at check-in for complimentary upgrades but have never stayed at the Aria so don't know if this is something they don't normally do (my experience with the Cosmopolitan, for example, is that there are no complimentary upgrades). I'd rather not pay for an upgrade that I could get for free if available. Any input would be appreciated.
Thanks in advance.
