A quote given to me by a Insurance Lawyer for Event Planners Association in America said..

"The typical bounce house company in this country is NO GOOD"

So remember that not all businesses are the same.

Regulations and standards vary between all operators. What you have to consider is what sort of company are you going to rent with. If you are an inflatable company what sort of safety commitment are you going to give to your kids and that of their little friends.

If your budget does not permit you to do it safely, then don't do it at all.
