I left service 1972 honorable discharge 4 years of Air Force service. Can I make use of this service

In order to use any MWR related service/facility of the US Military you need to have a current Military CAC Card (Active Duty or DoD Civilian) or a Retiree's or Dependant's Id Card. The only other way possible to use these facilities would be as a guest of someone who does possess the fore mentioned credentials

Only current active members and you need to reverse 6 or months in advance because the demand is so high.
