Look at the dead and dying Priority Club threads to see where an attitude like the one discussed above leads you.
Recent threads have focused on who had the most numbers of stays prior to abandoning the program.
There are no colder words than displaying a card that represents you spend 90+ nights a year with a program and having the desk clerk toss the card back to you with a "I gotcher number already". This program should be the poster child of curing brand loyalty.
So I think that sa long as I have choice of where I stay, you either give me a reason to return, or hold open the door for me on my way out.
