Olde Mistick Village and Mystic Aquarium are all aglow Friday when they hold their Festival of Lights.

More than 4,000 luminaria will light their walkways, and the Meeting House will host a performance by Ragtime, Too and refreshments for all. Entertainment will abound around the village, with Fly-by-Night Comedy Jugglers, well, doing comedy and juggling as they walk about the site, and the Festive Brass Ensemble performing in the gazebo. Choirs from Tyl Middle School, Montville High School and Ledyard High School will sing as they stroll through the village.

And, yes, Santa will be there, and he (and Mrs. Claus) will be available for photographs from 6 to 8 p.m. at the Village Green.

Festival of Lights — dusk-9:30 p.m. Friday, Old Mistick Village and Mystic Aquarium, Coogan Boulevard, Mystic; oldemistickvillage.
