Long Island Tent and party rentals. TheBigBounceTheory is proud to offer tents, tables, and chairs to the Long Island market. We’ve spent quite some time doing our research to find the best tents out on the market today. We offer the most popular style of tent for backyard parties, classic Frame Tents. With both 20ft and 30ft configurations, we’re able to accommodate most back yards in the long island area. And unlike the other guys……WE DON’T DO POLE TENTS……!
