If you're going to visit New York City and would like to see a few Broadway shows and you weren't satisfied with "Broadway: Where to Buy Cheap Tickets"—I wasn't either—check out the following sites for the cheapest tickets for the hottest and/or longest-running musicals:
Visit this site for the most complete list of what's currently showing and what's coming soon, so that you can plan accordingly. It's just too bad that I won't be around when A Chorus Line, Les Miserables, and Mary Poppins open. The Fantasticks started previews tonight, but the tickets are too expensive for previews of an Off-Broadway show that I saw in its original incarnation. And did you know that Legally Blonde will be a musical by next year?Talkin Broadway
Provides the basics (i.e., address, sked) for most Broadway shows and info on availability of "rush" and "SRO" tickets. These tickets are sold only on the day of the performance, and may not always be available. Rush tickets are usually for front-row seats where you will most likely not be able to see the entire stage, but you will see the actors up close. SRO tickets are for designated spaces at the back of the orchestra or mezzanine. Prices for rush/SRO tickets range from $20 to $25. Policies vary per show. See the FAQ for more information.New York TV Show Tickets
The name is a misnomer but the site has a table that shows the availability of discount codes and rush/SRO tickets. You may want to buy access to their Discount Broadway Ticket Guide ($4), but once you know what's available for which show, you can just head over to BroadwayBox.com for the codes, or Talkin Broadway for the rush/SRO info.TKTS has half-price tickets for reasonably good seats, but the cheapest tickets for the best seats in the house, in my opinion, are the rush tickets. Go to the sites I mentioned above, but it's also good to visit the theaters and ask at the box office because policies may have changed since the sites were last updated. To find out where the theaters are, go to the Times Square Information Center and get the print copy of the free map of theaters.
Finally, if you're going to see more than one show, I suggest that you take some time to do some research on the musicals you'd like to see, and visit TKTS and a few theaters to get a feel for the kind of lines and/or lotteries you'll be encountering. Break a leg!
