Next year we are making kids second trip to WDW. I have DSis picking up autograph books for me tomorrow so each of the kids will be doing that but now today we were at my grandparents house and DD fell in love with my grandmothers Disney pin collection. I talked to DCousin (Disney lifer) and she feels that the kids would greatly enjoy pin trading. I just have concerns that giving the kids autograph books and pins/lanyards would be too much for them to carry (& I would end up carrying it) and too much for them to leave somewhere. What are opinions on this?
