I'd definitely recommend European Aviation in Bournemouth for the MCC. I did my MCC there on the 737-200 towards the end of 2007. The Tri-Star Sim had broken and they had started to use the 737.
Although the MCC as some people have mentioned is just a tick box on your licence,getting experience on a full motion sim will be invaluable for any sim check you go on to do. It was my first experience of handling a real simulator and it was an eye opener,more so than I expected. For the experience of that alone it's worth doing it here.
The instructors & sim engineers are also first class,huge amount of experience between them and very relaxed friendly atmosphere. The course is more like a Jet Orientation Course and MCC combined,all the theory covered in the 3 days classroom reflected that.As some have already mentioned they do throw in extras in terms of time. EAC is also an airline in it's own right and most of the course is based around their procedures.
The airport is about a 10 minute drive out of Bournemouth/Boscombe itself. Easy to find a hotel B&B for about £20-£25 per night. You would probably need a car though. There is a bus out from Bournemouth/Boscombe to the airport but it only stops at the terminal which is on the opposite side of the airfield and quite a long walk over to the Western side were EAC is located
If you are planning on going for an airline post then make sure you do your MCC on a full motion Jet Sim,wherever it might be.
For my money it would be EAC in Bournemouth. I couldn't fault it
