Cyndilou,
Yes there where different places on the ship were you went to get a stamp. You had to answer a question on the map to get the stamp. Then you went to Mickeys Mates and got the free completor pin by showing your completed map. You could also buy the other pins that go on the map. You could take your time with the map, didnt have to do it all in one day, but it was easy to complete in a hour or so. Mickeys Mates is only open during certain times, and not when in port. So thats what caused the mad dashes as I call them.
I noticed you are making your own pin bag. I use the rigid felt (Stiffened Eazy Felt) that comes in 12x18 sheets for mine. I fold the sheet in half and trim to fit the binder if neccessary and then punch holes in what are the two ends, to place in the binder.
Hope that answered some of your questions. Feel free to ask away if you have more.
