My fiancee and I won tickets through a fundraiser that happened to be stage-side, and loved it. No idea if stageside vs "balcony" is worth it since I've only seen it once, but it's incredibly fun, and a really great evening. When we saw it, the actor playing Macbeth was the one to get drunk, and if they weren't just going by a script to make us laugh more, he had also been the one to get drunk at the matinee.
Definitely check out groupon or something like that just to get cheaper seats, but it's worth seeing for sure!
