Agree entirely - 2 hours in the 727 sim got me through the BAC1-11 sim ride as well. Before you go, talk to some other candidates and find out what the profile is (BALPA can help with this). Then get the Jepp/AERAD plates and plan it all at home. When you go to the sim you'll be able to ask the instructor for exactly what you want and you won't waste any time or money!
Good luck,
