Aria Comp & Cosmo Comp Can I book both rooms to use comps?

Staying at the Aria sky suites in Aug total comp, also just rec'd a 2 night offer for Cosmo for the same time we will be at the Aria, since they are right next to each other can I check in at the Cosmo the next day (will Aria know or care?) and use the 300 Identiplay credits they are offering me? My girlfriend who lives in Vegas would sleep in that room for 1 night so she doesn't drink and drive. Seems like a GREAT idea, but I don't want to piss off the Aria and not get invited back. BUT....since they are totally different why not? I know I can not combine 2 MLife offers at 1 time, meaning stay at the Aria and do a slot tournament at the Bellagio, type thing. Anyone know the answers to this???????

 

They are different hotels owned by different companies. No reason you cannot check in at both. All Aria cares about is your play. If you don't want to "piss off the Aria" then make sure the bulk or all of your play is there rather than Cosmo

 

As said, two entirelly different companies. Each company will evaluate your play based on your stay at THEIR property. They are competitors.

 

Thanks!!
