I also wished to do the MCC on a jet sim, but due to lack of funds went to Atlantic Flight Training at Coventry. They use a FNPTII with an exact Beech 200 King-Air cockpit.
Two and a bit days of groundschool covers the CRM and Human Performance aspect, then it's 20 hours in the sim, split 50/50 between PF and PNF.
Only two victims on each course, so you fly as a dedicated crew for the whole week. To be honest, having no experience of anything faster than a small piston twin, the workload on a King-Air is a big enough leap initially. Climb rates of 2 -3000 fpm on a SID combined with 300Kt+ groundspeeds in the cruise at times is enough of a challenge without wishing you were doing it in a 757. Clockwork instruments, basic autopilot and no autothrottle also up the ante.
Each daily sim session consists of two sectors, an 'out and back', with each pilot taking turn about as PF and PNF. Each pilot also has equal time on each side of the cockpit. Sectors tend to last an hour or so each, e.g. Stansted to EDI, for example. Later in the course weather and fuel emergencies are thrown in, making everything very realistic. The operational aspect is covered well, with computerised flight plans, company calls, pushback off-stand and pax announcements; all the stuff they didn't cover on the IR, basically.
Pete Humphries was the chap in charge, a bloke with a wealth of experience both in very fast machinery and as a turbine sim instructor. I highly recommend him.
