I have stated here many times active duty and retired. There are two time periods where other Veterans (separated but hold no ID) can book but they need a DD Form 214 to show upon check-in.
Rates are based on pay grade. Military IDs are
ALWAYS required upon check-in. Security guards also ask for your ID before entering the property. Our last two stays had a very strict female security officer who took her job over the top serious and verifying members. My dad came over from his hotel (sister was there with her school band) but he also has a retired ID. My adult sons came over to visit with us and Grandpa and only one of the two has a military ID and I was sure to leave their names at the gate to ensure they didn't give them any issues.
Each eligible person can book up to three rooms. For example, I am a retiree so I can book three rooms. My DH is a retiree so he can book three rooms. The eligible person must stay in one of the three rooms. We have never booked more than three rooms for one stay. Last March and May we booked three rooms and sponsored two friends. We stayed in one room and each of them in the other two rooms.
Shades of Green is a MWR hotel and if you are military you know what a MWR hotel is. Just like the Hale Koa in Hawaii and other military resorts.
Same website you referenced tells you who is eligible and required documentation.

January and September are the two months they open to other Veterans with honorable discharges.
