Generally at the Apod you are in two man corrimecs which are great as long as you keep the place tidy and the aircon does not break. If it breaks, then it becomes a sweat box.
On arrival you should get chance to buy a cheap fridge which is a must, especially in the higher temperatures of spring/summer. We kept ours stocked with coke and gatorade as well as water. Nothing better than peeling off the kit after stag/patrol etc and necking a ice cold drink.
Would recommend against getting brand new electronic stuff as the dust gets EVERYWHERE! you can get DVD players from the naafi out there, but not sure what region they are...
There is a bar on camp which is likely to sell beer and so on. Your OC will probably be the camp commandant so it will depend on him (and how you guys behave) if that bar remains open. The comment by Woody is a valid one. An NCO got a Â£1000 fine towars the end of the tour and was warned that he got off likely.
There is a regular laundry service, the LEC's are partial to fanta etc if your CQMS is on the ball, and manages to arrange for a 24 hr turnaround...
The efi is good, and worth a visit for the occasional boost of morale. There was a good choggi shop in waterloo lines for DVD's and so on, another good one opened behind the efi while we were there too.
Subway does a good breakfast if your willing to spend money, and Pizza hut deliver anywhere on the base.
