The type of party bus you rent has a big effect on the price. Party buses are built by many different manufacturers, so two buses that both hold 25 passengers can look very different inside and rent for very different rates.
Sprinter limos and small party buses are the least expensive type to rent. They hold 10 to 14 passengers and start around $210 per hour on weekdays. Most of them are only a few years old, so if your group is small, you get a new interior at the lowest rate on the page.
Standard party buses hold 15 to 30 passengers and cost $204 to $374 per hour on weekdays, depending on size. These are most of the party buses you'll see on Partybus.com. Within that range, the price depends on how new the bus is and who built it. A brand-new bus from a builder like LGE Coachworks costs more per hour as these are the nicer, newer buses available. Builders like Tiffany Coachbuilders, Executive Coach Builders, and Battisti Customs each have their own interiors and features, and you can see how they compare in our guide to party bus builders. When you're comparing two buses of the same size at different prices, this is usually why.
Large party buses that hold 40 to 50 passengers are rare, so they always cost more. Most operators own one or two at most. Expect to pay $294 to $441 per hour on weekdays and more on weekends and during prom season, when every large bus in a city is booked. If your group is over 40 people, book early or consider splitting into two mid-size party buses, which are easier to find and often cost less combined.
Whatever type you rent, fill as many seats as you can. A 45-passenger party bus at $325 per hour split between 40 people is about $8 per person per hour. A 20-passenger party bus at $250 per hour split between 18 people is about $14 per person per hour.
