As someone who worked at Frozen on Broadway for about two years, anyone who is able to see Caissie and Patti are in for a treat. This might be a hot take, but I prefer the Broadway version of Let It Go to the original. I may be biased, though. Getting to hear it live several times a week was an incredible experience.
I'll also be there during the Heidi & Gavin dates, so I'm planning to see them as well. Gavin was so perfectly cast as Bert in Mary Poppins. Thrilled to be able to see him again! And Heidi is wonderful.
I got to see Ashley/Michael and L. Steven/Mandi last year, and both sets were really great. I'm glad they're mixing them up this year, though. Keeps it exciting. Wish I could see them all. You really can't go wrong with any of the pairs, I assure you -- as an official Disney on Broadway geek.
