If you've read some of my other posts, you'll realize I've been performing magic professionally for several years now. Though I mostly do Gospel shows, children's shows, and birthday parties, I have done a few "close up" shows as well, for older children, teens, and adults.
My office has asked me to do a magic show for them in about 3 months. (some mid-Spring social event.) They want me to do my standard children's show for the younger crowd and have asked if I would be willing/able to do some "walkaround" magic for the adults as well.
I hesitate to say this, since I've read some of the other posts in this section, but
I've never done this before (gasp!

), but I would like to try it. (How else am I going to find out if this will work if I don't try it?)
Most of my close-up show can be adapted for in-the-hands, tableless, walk-around magic. I've seen other magicians do this before (though I didn't think some were very good!) So, here's the question (finally!)
If I draw a crowd of a handful of people at a time, how long of a "show" should I give them before I move on? I can make a variety of coherent, smooth-flowing "shows" that are only about 5 minutes long each (switching between them throughout the afternoon). But is that long enough, or should I expect to be planted in one place for longer than that?
Of course, I should be flexible and "go with the flow", but it would be nice to have some idea going into it. Any thoughts?
Thank you!
