I just returned from Guam (TDY).
Here are some of my general impressions, in no particular order:
Tumon Bay is fun; great beach, good bars.

There is a reason you get 2nd year pay immediately and the living allowance: things are pricey!

If you have kids, run away. The schools are not just bad; they are dangerous.

The base currently does a surprising amount of night flying. Not one of my trips got back before 01:30, including the turns. I was getting back to my hotel between 02:30 and 06:00.

The over night hotels are great! They better be, because in many of the cities
we RON, it's best to not carry any jewelry, phones, wallets, etc, while going for a stroll.

The Air Micronesia community is terrific. The best flight attendants in the system. They are not going to give you cockpit massages, but the truly are very friendly.

Biggest damn spiders I've ever seen!

Lots of tourist everywhere! Japanese, Korean, and the new kids on the block: hordes of Russians.

I did not see one bird. The brown tree snakes got 'em all.

The hot spot in town is the local 24 hour K-Mart (I am not kidding).

I had fun while I was there, despite the horrible duty hours. I would not want a steady diet. Once the novelty wears off, it's sure to be a bit of a grind. I can imagine that in the summer , when it's 99 degrees, with no breezes blowing, it would be oppressive.
