Don't feel bad. There are too many good shows to see them all. I've been getting to New York at least every 2-3 months and I still miss them. You've made good choices and I hope you have a great time.
Currently on a bway trip from Toronto too and I saw spring awakening Monday. And I'm just going to say save yourself..go see curious. I have never had a worse night in the theatre than spring awakening. Just avoid at all costs.
