In my opinion, you should be able to use 20 of them on a 1 nite stay for a $2000 Presidential Suite.

In my experience, I've been able to use 1 per 2 nights stayed in the hotel. For example, I used 2 Premium Pounds on a 4 night stay last month. One reservation: no need to break it into two separate two-night reservations and have a little check-out-check-in ritual in the middle.

However, given the fact that many clerks have never seen these certs and aren't too familiar with how to process them, it wouldn't surprise me if someone else has had a different experience. I believe what I did - using 2 certs for 4 nights on 1 reservation number - was totally within the rules though.

Sorry...whenever someone says "I don't want opinions", the first thing I feel the need to do is express my opinion.
