I was there Feb 2002. Had a great time, very laid back but professional. I did my IR there and was ready for test in just over a week! But I was on the old system of Training as required! The Sim is almost identical to the aircraft as long as you are doing it on the Cougar, which is a lovely aircraft. I have not a bad thing to say.
Don't be put off by the cabins, they are a warm bunch of guys and you wont feel pressurissed there or overwhelmed which makes you learn alot quicker.
Have a fun time, the IR is a great rating to do!
