Actually, on the 1st year there are 13 stage managers and I think for the technical courses, the ratio is about 1:60 or higher, for the acting courses 1:100. I may be mistaken.
Anyway @03lawrel
You won't have classes with 50/ 60 people. You will be divided into much smaller classes, it's better to work, and will usually swap, so you still will be in working contact with all the people on the course regularly, but it won't be inpersonal as you assume. My flatmate is on the DATE course and she loves it, they have off much more days than the acting and theatre practice students, so she is currently working on another performance a 3rd year has set up.
Central is amazing and a nice light building, I very appreciate, and provides you loads of gorgeous opportunities, yes, London is more expensive, but for a drama student the paradise!
It comes really down to what you prefer personally and Central will have or make you do stuff you will probably dislike, but that is the case at every instituition, you have to grow with it.
Look again at the course description, make a budget, leave the prestige and flattering part by side for a moment. It might be, that Central opens you more doors, but in the end, you have to be good, wherever you went. And as soon you start the course, you work from the very beginning, it is just even harder.
