May I make a suggestion?
Although I don't see anything truly wrong w/ seeing one show multiple times, why not share the wealth?
There are many other theatres in NYC outside the Broadway houses. And usually, they are a lot less money. If you truly are a theatre supporter, then you should consider spending some time in the off-off Broadway world. The production values are never particularly high, but then again, neither are the tickets! And you run the chance of seeing some wonderful things. Think if you got to see the original URINETOWN, before anyone knew what it was.
Or perhaps the recent, award-winning revival of THE BEGGARS' OPERA.
There is some terrific talent in this city, and a lot of it has not been discovered yet.
