this is an excellent example as to why one should present these at check in

I always

1. Make a copy for my records of the PP used
2. Present the PP at check in > have them initial the copy as rec'd
3. Request a printout of the credit received (conversion rate)
4. validate on the bill under the door it was applied either at all or properly


the reason I do this is so that I can dispute any issues on the conversion rate; that they did indeed receive the PP and apply it and it allows me the duration of my stay to get it straightened out

this just adds another reason as to why I should continue to use this process and never wait until check out to do this
