Are 100% permanent disabled veterans allowed to use the facility?

As long as you have a valid military/dod ID card

Yes they are but with the Military I.D. that says rank and indifinite on expiration date not the VA card

Yes all personnel with an id card can use it

Like they said, bring ID, and you can't stay overnight. But yes, you can.

DOD card

Retired military (Blue ID card). But you cannot stay there from 2200-0600
