Hi,
We just came back today from the Western cruise, where my DD became quite familiar with pin trading.
She first read about this activity on this message board and bought a small selection of pins in the Orlando airport.
As already mentioned there will be organized times for trading. On our cruise I think it was 7:30 to 8:30pm most nights. Then there was a special day to trade with just the ship's officers, but many of the crew wear their pins all day and will trade on the spot.
As a matter of fact, as we were welcomed onto the ship, my DD saw a pin she liked on one of the welcoming crew members and he traded with her right then and there. As for cast members specifically, I do not remember any of the characters having pins, but some of the other perfomers did, and when my DD saw them around the ship they were glad to trade. Even some of the shop keepers in Grand Cayman had pins to trade.
My DD collected quite a few unique pins from the cruise and the crew were more that willing to trade.
Considering she was a novice at pin trading she avoided the our fellow passengers who were more serious about their trading.
There were many folks with books and bags full of pins, they were most experienced than my DD and she prefered to trade with others in a less organized manner.
She seemed to have alot of fun with it.
thanks
