If I ever moved back to Miles City (and there is very little chance of that happening) I would open a franchise of this business:http://www.pumpitupparty.com/
Franchis Opportunities: http://www.pumpitupparty....rview.aspx
The good thing about a franchise is that someone else has already shelled out the money for advertising, printing costs, etc. and the business has been successful many other places.
Miles City is the perfect place for this business, since there are always a lot of kids and families there, and at least half the year you have nowhere indoors to take the kids to let them wear themselves out with exercise. There are indoor obstacle courses, slides, bouncers, boxing rings (heavily padded) and a gladiator type ring where the kids can knock each other off the "hill" into a padded area.
I think a lot of people want to throw nice birthday parties for their kids, but if the kids are born in the wintertime (or the hottest part of the summer) you can't take them to the park, and who wants a bunch of energetic kids rampaging through their house? The Airport Inn is a lot of fun, but not great exercise for kids.
They charge so much per kid for birthday parties and have some sort of a deal with the local pizza place so they get a percentage of the food served at the party as well. Also, they are very organized so that you can have a great party without spending a week before the party getting ready and then a week afterwards cleaning up.
The kids here all LOVE this place (when my daughter was a pre-schooler we went to the "pop-in-playtime" every time it rained or the weather was bad just so the kids could get some decent exercise for that day). All of the Moms could keep an eye on the kids and have a nice visit at the same time. One of them even brought her computer and did some work while her son had the time of his life!
Out where I live you can have birthday parties year-round at the beach or the park, but it is just easier to bring the kids to this indoor environment and turn them loose to jump until they are exhausted without worrying about them falling out of trees or leaping into the ocean (while the parents have a nice, uninterrupted visit!)
