Without carnivals, grownups could only relive their childhoods by wearing oversize trench coats and pretending to be two kids pretending to be an adult. Step right up to this GrouponLive deal: for $20, you get two all-day passes for adults or children to the Port of San Diego Festival, presented by Maxx House Entertainment and held at B Street Pier from Saturday, June 30 to Sunday, July 8 (a $40 value). The festival will be open from 10 a.m. to 8 p.m. on Saturdays and Sundays, from 10 a.m. to 10 p.m. on Wednesday, July 4, and from 10 a.m. to 7 p.m. all other days.
Nonparticipating parents are admitted free. Guests should bring a swimsuit for water attractions, and changing stations will be available.
To ring in Independence Day, Maxx Bounce Entertainment unfurls a prodigious fairground of inflatable obstacle courses, water slides, and bounce modules. The centerpiece of the spectacles on hand, the self-proclaimed World's Largest Inflatable Water Slide whisks kids, adults, and smaller inflatable water slides down its three-story, 175-foot length. The slide is not the only attraction of prehistoric proportions—a lifesize T. rex towers over a bouncy Cretaceous-era jungle for children, and the festival's largest dry slide takes the form of a 35-foot saber-toothed tiger. Those who redeem their day passes on Wednesday, July 4, can cap off the day of aquatic fun with the Big Bay Boom fireworks display, as it lights up the night sky and sends thunderous claps over the harbor's natural amphitheater at 9 p.m. The pier will be packed every day of the festival with food vendors, face-painters, balloon artists, and a miniature train that traverses the fairgrounds just as the transcontinental railway first shuttled passengers to the surface of the moon.
