On this one "rare" occassion, I agree with Mark. There are people in the USA who do the whole sha-bang, but I think you need to decide who you are. Are you a Magician, or a Party Planner (for lack of a better term)?
I for one would never have anything to do with games and crafts, and other stuff. If I were a clown then perhaps I would do that as that seems more "clownish" to me.
I want to get in, do my thing, get my money, and get out of there. I usually have several shows booked in a single day and if I don't, I need to get back to the restaurant to perform. For me, time is money. The more shows I do, the more money I get.
So IMO, the 2 hour show (games, magic, balloons, crafts, etc) just won't work for me.
On a slightly differnt subject I'll tell a brief story that you might find humerous. While living in Virginia, there was a Magician who would advertise that he could perform a 30 minute show or a full hour show. The price difference was $100.00.
The difference in the show...NOTHING! The 30 minute show was his standard show. The full hour show was still only a 30 minute show except he would produce a bunny for his big finale and for the remaining 30 mintues would let the kids pet the rabbit.
American's by design are very lazy. I know cause I'm one of em! We work extra hard thinking of ways to be indolent and get paid for it.
Another little bit here...
How many times are you asked by someone (young or old) if they can show you a trick while you're on the clock. You hate it don't you? I use to keep 21 cards banded together in my pocket and toss them on the table when asked. It was joke, but usually that was the trick they were going to show me. It quickly defused the issue and I could get back to work.
A friend of mine out here in Dallas told me that anytime he's asked, he let's them do AS MANY TRICKS AS THEY WANT. He's on the clock getting paid regardless of whether or not he's working. His job is to entertain which he's doing by letting this person show him magic...so he tells them to take their time, do several tricks, etc.
So like I said, out here in the US, lazy sells! It's sad really...
Off to slumber...
