In roller skating, as in dangling from the edge of a cliff, it's important not to let a fear of falling make you miss an opportunity to hold someone's hand. Don't leave today’s Groupon hanging: for $25, you get $50 worth of activities at Interskate 91 in Hadley. This Groupon is valid toward:

• Rink & event admissions
• Skate rentals
• Skating lessons
• Laser tag
• Birthday parties

After the first visit, any remaining Groupon currency transfers onto Interskate 91 gift certificates for future skate dates.

Visitors to Interskate 91 can zip around a huge rink, lauded as a top skating destination by USA Today, or dodge futuristic enemy fire in a laser-tag course. After lacing up a high-performance pair of skates ($4.50/rental), eight-wheelers can moonwalk to dance hits from the ’80s and ’90s on the rink’s Thursday Retro Party night ($6 admission after 6:30 p.m.), while DJs flash lights and spin Top 40 tunes during Saturday-night Jamz ($9 admission). Alternately, 22nd-century-themed laser tag ($6/20 minutes) transports youths to the future, where they fire harmless laser light at one another to train for the coming rebellion against humanity’s mutant-hamster overlords. Groupon-holders can also put Groupons toward birthday parties ($14.95+/person) and skating lessons.
