I've thrown two Build-A-Bear parties, and I'm going to have my third there in April. First and foremost, the Build-A-Bear parties are VERY popular, at least around here. They usually fill up abut 3 months in advance here, and sometimes 4 months. We've always set a spending limit, and make it clear to the party leader. I've never had a problem with the children going over it, though I've had problems with the parents allowing their kids to pick out other accessories (ones I'm not paying for) and then paying for it themselves. It makes some of the other kids feel bad, those who's parents won't spend the extra $30 or so for every other accessory. I've done a $15 limit party and a $25 limit party, I will say the $25 limit party was MUCH better than the $15 limit party. They were able to pick any bear up to $15 and then were able to get an outfit also. I'm doing DS's party there in April, and I think I'm going to go with the higher limit. Also, my parties have always been over 20 kids, and they have NEVER gotten out of control, and the party leaders always did a great job keeping them in control and within budget.
