Hi,
Sitting in the cafe does work but I think you miss some of the magic... it only took 10min to get tickets - and if you get to the theatre 20/30 min before the show, you get to sit centre front where the actors really interact - Scar comes RIGHT up to you!!! You feel more like you are really part of the show when you get the tickets. Also at the end the actors go up and down the aisles of the theatre bit and pose for your camcorder etc on their way, so I wouldn't like to miss out on that...
