LMS, it's not a dumb question and, having been there a couple of times now there are a few peculiarities to the place. Melchett got the attitude about right though for a sizable (though not all) portion of people there.
The facilities are good, air-conditioned accommodation, reasonable food, usual collection of spam concessionaries - BX, Pizza, 'local' shop, tailors etc and the BFOT beer venue. The gene pool is the only place to get a tan (local sensitivities to be observed) and ablution blocks someway from accommodation requires appropriate footware!
The real art to survival there is to resist the undying urge to throttle some of the jobsworths that inhabit the place
You didn't say when you were going. Assuming the usual PMA notice period
you'll be there Feb-May and the temperature will be starting to rise to mid 30s by the time you leave. One of the biggest problems is the predilection of the colonials to turn every office into a standby meat locker with the air-con. Walking in and out of it all day causes more problems than it solves.
Get past the bullsh!t and enjoy it - there's a lot to learn outside of whatever spec you're in and, not being a home base, most people are keen to show/explain/discuss what they do.
