A party bus is a small bus turned into a mini-club on wheels. For one thing, party buses have the perks of a limousine but they are spacious enough to dance and move around. Depending on the size and accommodation of the bus, they have one or two dancing poles. Such poles also serve as a safety precaution as people stand around and dance in the moving vehicle. The best party buses have lights, an excellent sound system, cooler, screens, and an expert driver.
