I was at Guam for a military exercise at Andrews AFB in 1990. The actual exercise didn't start for about a week so we had a lot of free time.
The climate was very tolerable, the beer was cheap, and the snacks were free (fresh coconuts right off the tree). There was a beach for the AF guys nearby and it was easy to get a ride there and back.
I'd never been in the tropics before (or since, for that matter) and the short transition between daylight to dark came as something of a surprise. We were billeted in an ol barracks that had no glass in the windows -- just screens and metal shutters. The "PEEP!" of geckoes kept us awake at first, but when we heard that they'd eat the mosquitoes, we welcomed the sound.
As much fun as Guam was under those circumstances, I suppose that would'a been even more fun if I was staying at a hotel.
Just my 2ยข.
