Long Beach Unified School District covers some of the largest high schools in Southern California — Long Beach Poly, Millikan, Wilson, and Cabrillo among them — and prom season (late April through May) is when every party bus in the South Bay books out fast. Schools routinely hold their formals at venues like the Westin Long Beach (333 E Ocean Blvd) or the Terrace Theater inside the Convention Center, and the demand window for those weeks is narrow and unforgiving.
For prom: book by January or expect premium pricing and reduced availability by March. A 6-hour prom rental for 30 students — school pickup, photos at Colorado Lagoon, venue drop-off, and after-party return — typically runs $1,800–$2,200 when booked four to six months early, versus $2,800–$3,400+ if you're calling in April. Party Buses Los Angeles works directly with parent committees across Long Beach and the surrounding districts to coordinate multi-bus prom nights.
