As with many things, loads of us see the NRM as a 'different place' to the thousands of people that actually go there. We are a minority that can satisfy our need to perhaps witness Engineering at a Heritage Railway.
It's the same with many of our views on Heritage Railways as well. The successful ones run as well managed businesses. Businesses need to make money and many of those money making activities involve jolly activities, food, drink, and imaginative marketing. We may not like Purple Bulleids or inappropriate stock etc. However, punters want a good experience and will pay for it, especially if the reputation of the success of said experiences is well sold.
Striking the balance at somewhere like the NRM requires a Business Head that recognises the best ways to keep the place afloat.
If that means loads of seating and rather gimmicky selling areas then who am I to complain?
