I did mine there, a few years ago now (2008) and can only echo what was said above, great place with great staff, nearly an interview with them to but didnt have 500 hours, one of them situations where the chief bod popped his head in and said 'I've heard you're all good guys anyone with 500hours?' This was when they were running 737s for Palmair
I stayed in a caravan on a site about 2 miles away, literaly at the threshold end of R26 if you look on google earth, cost £10 a night in one of their caravans.
Even though the course didnt run at weekends I'd stayed over and was allowed to sit in the sim motion off or if it was in use then the cardboard version so as to familiarise myself and run through touch drills.
As for the complex aircraft worry, there isnt one, you learn your stuff and go and put it into practice, it flies like any other aircraft and as its not a type rating you're not bogged down with T/R stuff, its learning how to work multi crew and thats what matters. For what you do in the sim aircraft wise its no more complicated than what you've done previously, just with another person, crew & pax to bring into the equation and the benefits and possible pitfalls that can bring.
I also saw it as a point on my personal learning curve, a next step/challenge after twin piston I/R and felt a full motion jet would be a great experience and an insight into what the future holds When I stepped into the cockpit it felt like an achievement on its own that I'd gained a qualificaion that allowed me to be there...might just be me but there you go and it was good for motivation for the hardest part, 1st job!
The MCC for me was the most enjoyable part of training.
