They have like 4 different birthday packages, ranging between $145 and $250. Every package includes two hours of trampoline access (you get a party room for 1hr45mins during that 2hr slot), 2 pitchers of drinks, and jump socks for each jumper (up to 10 unless you get the biggest package.)
When we did ours it came out to about $250 for 10 people for an hour, including the pizza.
