Long ago there was a place where you could print out a membership card, but recently I have been unable to locate it.

I was sweating bullets when PHT asked for proof of membership during check in, because rack rate was nearly triple the price I'd booked over a year in advance. Took nearly ten minutes for me to dig up the original enrollment email (thank goodness I am an email pack rat) that I forwarded to the hotel, and they accepted that.
