Without dedicated bonding time, family members grow resentful of one another's bad habits, such as cheating at Monopoly and warming socks in the toaster. Preserve familial unity with today’s Groupon: for $18, you get one Midway to the Max unlimited-indoor-activity pass at Midway Family Fun Park in Ottawa (a $36 value).

Dedicated to fostering imaginative playtime for children, Midway Family Fun Park’s 50,000-square-foot space bustles with young adventurers climbing, jumping, and riding on a slew of indoor attractions. Holders of a Midway to the Max unlimited-indoor-activity pass can spend a full day getting a taste of grown-up life by piloting bumper cars or boats and discussing tree-house mortgage rates with fellow drivers. Well-trained employees oversee the indoor kiddie train and helm the 25-foot rock-climbing wall to ensure the safety of all scalers; young sprouts can also hone flexibility and balance amid the jungle gym’s ball pit and slides. Outfitted with a number of obstacles and commentary by tiny announcers, the nine-hole mini-golf course grants clubbers a chance to show off their putting prowess on scaled-down greens. Guests also have access to the bustling arcade, which requires tokens for play (not included with today's Groupon).
