For the first time, Universal’s Islands of Adventure will present its Grinchmas musical indoors. The production, which includes music recorded by Mannheim Steamroller and featuring the “How the Grinch Stole Christmas” story by Dr. Seuss, is part of Universal Orlando’s holiday celebration, which kick into gear Dec. 4. This year’s production will be in Soundstage 20, according to the Universal Orlando website. In previous years, Grinchmas was staged in a nook behind the Cat in the Hat attraction. The move should allow for climate control and an increased amount of seating. Show times for the Who-heavy musical are noon, 1 p.m., 2 p.m., 3:30 p.m, 4:30 p.m. and 5:30 p.m. Dec. 4-Dec 25 and Jan. 1.
