$20.or higher tip at Aria

I posted this a while back but hadn't received any comments, and would really appreciate advise on this. I currently have two rooms booked at the Aria for November 11,12,and 13. Would it do any good to tip say $50.00 for an upgrade on both rooms ? Has anyone tried this at the Aria ? If you think this is a waste of money I won't do it ? Again I would really appreciate your comments? I will be in Vegas with son, son in law, granddaughter and a friend. If we can't get an upgrade I hope a request for both rooms to be on the same floor will be honored. We will be arriving in Vegas around 3:00pm.

Don't think I'd start with 50.
They may take it, and you get a smile only in return.

I believe in tipping After I get whats requested........most of the time No tip required,
just asking nicely.

If checkin jumps thru hoops for ya? Fine, Give him/her a $20 is nice, appreciated.

Thats just me. I've only had to tip a couple times out of couple hundred checkins.

What she said.

Ditto.
Twenty is plenty!

Fifty is well...forgetaboutit.
