Stoneham Theatre contributes to the seasonal vibe with a stage adaptation of Miracle on 34th Street (November 29-December 3), and North Shore Theatre mounts the Christmas Carol to beat (November 30-December 30) -- loaded with special effects and extra-lively in the round. Trinity Rep's version of A Christmas Carol (November 16-December 30) -- now in its 31st year -- is also a pip. The show is so popular, it requires two casts (25 members strong) in constant rotation.
