Help, Going to WDW in 2 weeks on a shoestring budget and need advice. I have three Little People (8, 7, & 5) who are about to bust with excitement and I need to find a way to let them experience pin trading. We have had friends tell us that this was so much fun for their Kids and we must do it. So, how can I get some of these pins CHEAP and how many do I need? Can I buy them offsite or before I leave home somewhere?
