I used the $20 tip 5 years ago at Treasure Island. I got a upgrade. Now five years later I am going back to Vegas with my husband for our 20th wedding anniversary and also my husband's first visit ever to vegas and want to give the tip a go. My questions are as follows: with inflation should I try and tip more or stay with the twenty bones? We are planning on going at the end of April and where planing on getting a lower level tier suite so would my chances be better getting a better suite or should i book a regular room and hope for a lower level tier? I hope this makes sense because when I read it I sound like a idiot. Thanks
