We're looking to book a fun truck for a PTA event in Pasadena on Sept. 24th. It's not a fundraiser, but we have a lot of families with lower incomes so we're looking for a price point about $20-30 per family. It's also not private, so potentially we could have other members of the community participate. Do trucks do this kind of thing? Or do most of them require advance payment? Thanks for the help!
