My kids have about 90 between them, but many are just the trader pins they got online. They did a little trading, but DD9 mainly traded a trader for a trader.
I have 13. One dated pin for each year we’ve been there, one for the Resort we stayed in two of the times and one from each of the main park. I also bought the boxed set of the fourth of July pins this year because they ran out of the single pins. My favorite is a pin of Mickey standing by a framed pic of Walt.
Next year I’ll get one for POR if they have one, a dated one and otherwise we’ll just have to see.
