Some of us call monthly community dances at the same venue, and a few hundred dances, as Paul suggested, might be good for us.  
Like Karen, I do tend to call the same dances at most of my One Nighters.  I slowly add dances to One Nighters, and occasionally remove them from the least.  If I have an annual One Nighter, I generally repeat most of dances from the previous year and add a few new dances to keep it fresh.

I just reviewed my own list. There are about ten dances I typically use for a onezie or community dance, and if there are demographic changes (ages, dancing capabilities) I might add a couple more.

A hundred dances would be overkill, and leads to the sort of "dead air" I've witnessed at onezies lead by others. If you have too many choices, you'll never have the perfect dance.

Here's a thought -- the link below shows "muddle and match" books for kids. Infinite combinations, just turn the pages and pull together some random combo for figures. (Some folks do this with fakebooks so they'll have a bazillion sets of medleys.)
