I have PP Select card via my AMEX Hilton CC. I just received my card with a new expiration date. In the attached letter they note: "You are entitled to 10 complimentary visits per year....You will automatically be charged $27...after your complimentary visit allocation is used." I don't recollect seeing this restriction before.
I saw that restriction last year when I got the Amex Hilton. I leave that PP card at home and use the one I got from Chase Sapphire Reserve.
