I have only had a chance to use it in Vegas once (and will on Sunday).
Hotel: Paris
Date: April 94
Airport check-in
I think Priscilla was her name
Yes it worked
offered $20, and she didn't pocket it until she was sure she could do something
updgrade: regular room to Strip view room overlooking pool and
Bellagio fountains and able to get into room at 10:30 AM. Other people on our shuttle were discussing what to do until they could get into their rooms in the afternoon.
Since then I have tried to upgrade at EVERY hotel I have stayed at no matter what city. Most of the time with $20. (sometimes I just ask if I am looking for a specific location/side of the property) and it has always worked.
General advice:
From what I have read here and several other boards, inventory is a big key to the $20 trick. They can't give you what they don't have. If you don't get an upgrade, most of the time it will be due to this.
Make your request as specific as possible, know the room type names of the hotel you are going to (P room at
Paris, GO room at
Flamingo etc.) and the location you would like (overlooking to Pool, Strip etc.) I have seen many trip reports with pictures and links to on-line photo albums referencing exact room numbers. Can't hurt to say, "I was wondering if there were any complimentary upgrades? I would really like room #3460 or something just like it if possible."
