The thing I have done is collect Disney World pins. I believe I have about 50+ I also bought a pin collecting book to put them in. Some are cheap, others are quite expensive but you can get one to represent each park, each resort, and many if not all the rides and restaurants… Many people collect and trade pins at WDW. You may notice that most of the CM’s carry them on a lanyard. You can trade pins with them or you can trade pins with whoever sees your lanyard (if you buy one). Many of these pins are the cheaper ones and mainly for trading. Other pins you will not want to trade but keep them as a reminder of your trip. There was an old tradition of collecting spoons and many do that. I think however that pins are the way to go. If you don’t like them anymore, most will put them up for sale on ebay. You generally will NOT make money on these pins or very little at best, so if you buy them intend to keep them as collectables. If you should get into pin trading, buy the cheap ones via ebay as you can get them in bulk for very little money and these are what everyone goes around trading. It can be quite fun especially for the kids.
