350$ for an hour for 12 people. Some other things like 45 min of party room use. I don't know if the socks are included. Just jump and ninja course, in this package. Some food options included. https://bravoz.com/parties-group-events/birthday-parties/ shows some options for costs and features
If you already have socks, then you don't have to worry about buying more. I would definitely get the the other parents if they are coming to chip in. But i also have 4 kids so thats just my opinion.
