Spring break at New York City public schools helped Broadway stay warm last week, as families with free time and new shows gaining momentum — like the well-reviewed revival of “Skylight,” pictured above — kept numbers robust.

“Skylight” ($749,843), the revival of the David Hare play starring Carey Mulligan and Bill Nighy, gained 20% compared to the prior week, fueled by the enthusiastic reviews the show earned following its April 2 opening. Also gaining steam was previewing musical comedy “Something Rotten!” ($619,159 for seven previews), up 22% despite playing one fewer performance than the previous frame.

Other titles adding to the Broadway pot included shows ramping up to a full schedule or gaining momentum (or both), including “Gigi” ($635,256), rising despite accommodating an opening night and press comps; “Hand to God” ($282,901), also up in its opening week and likely to go higher on the backs of strong reviews; and “Fun Home” ($401,034), which opens Sunday. “Finding Neverland” ($1,129,481) barely budged, despite all the press tickets handed out in advance of its April 15 opening.

Recent Tony winners such as “Beautiful” ($1,057,902), “Kinky Boots” ($1,082,034) and “A Gentleman’s Guide to Love and Murder” ($712,576) also bumped up notably, perhaps indicating that, at this point in their lifespans, those shows pique the most curiosity among more local Broadway spring-breakers than among tourists from farther afield. The well-reviewed but often sales-challenged revival of “On the Town” ($752,482) climbed by almost $190,000, one of the biggest sales jumps of the week.

Among plays, Larry David starrer “Fish in the Dark” ($1,169,986) and Helen Mirren topliner “The Audience” ($1,143,548) led the pack. “It’s Only a Play” ($694,877), with Nathan Lane back in the title role, climbed significantly, even though Lane was out sick for one performance.

Overall Broadway sales held steady at $29.5 million for 35 shows now running, with attendance rising slightly to about 297,000.

With the spring break season mostly passed, overall Broadway sales will likely slip somewhat this week, but good press for shows like “Hand to God” and the just-opened “An American in Paris” ($826,417 for seven, including opening and press perfs) seems sure to push individual titles higher.
