My first stays were at the Park Central Marriott in Dallas (long gone from the chain) in the early-mid 80's. Not the greatest hotel but I signed up for this new "Honored Guest" program which, at the time, allowed you to double-dip 1000 Delta miles with your stay. I learned quickly about loyalty and building points, even though I did not ever earn elite status (Black level, I believe) in the early program. Redemption was much easier back then and I enjoyed some pretty good vacations.
