OK, I understand what you're getting at. I was a little worried that you thought OAT's FIs were getting 30k more than anyone else's!
I don't doubt that some of OAT's expenditure is little more than window-dressing. Every organisation with something to sell does it to some extent. On the other hand, I am sure that much of it is spent in order to provide the best learning environment they can. Naturally, there will be more than one opinion on what constitutes the best learning environment, but that's why there's more than one school to look at.
Do they offer more than any other school? Well, that's what you have to decide for yourself. It may well be that they offer more than you need or want. It may be in some areas they don't offer enough for your needs. I hope your choice works out well for you - and I hope the debt doesn't cripple you for too long!
