In the event of any damage to the party bus,, it is important to refer to the terms and conditions listed in the hire agreement. There should be provisions there that apply to such situations, which may involve assessing the extent of the damage and determining the liable party. Most rental agreements require a security deposit upfront, which can be used to cover any damages that occur during the hire period. If the damages exceed the security deposit, you may be responsible for paying damages. Some companies offer insurance options for an additional fee, which can provide additional coverage for damages.
