New experience or old favorite?

Much like how I keep saying that I want to go various places in Europe but always wind up back in London, I have a tendency to be like, "Ooh, that play/musical looks good!" and then see the same shows that I've already seen. Lately there's been a lot of theater I was interested in--Christmas Carol 1941 at Arena, Nixon's Nixon at Round House, The Visit at Signature, that play about the American who gets sent overseas where most of the dialogue is in a made-up language. And what did I see? Hairspray.

It's happening again, too. I see that Olney is doing Big River, which I've seen a couple of times and love. I'm really tempted to see it. They're also doing The Mousetrap, which I'd also like to check out. I should go see The Mousetrap, if I'm going to see one, but...I don't know. Of course, maybe inertia will win again, as it has so often lately, and I just won't see anything.

(Also tempting? Les Mis at Wolftrap the end of the summer. It'd be my, like, 9th time. But it's been years since I've seen it last!)
