We just did this for our early June vacation; got an incredible deal that I couldn't pass up. We walked from the Poly [I did ask for directions there - it can be a little tricky to get on the right path] and the guard at Shades of Green didn't even ask us what we needed when we walked onto the property. But, I had my reservation with me just in case. You do NOT have to be military to rent a vehicle from that location. It was as smooth as possible and I would not be reluctant to do it again for the kind of savings I received.
