The DW

& I

will happily organize the FE exchange for our cruise.
I think the easiest / safest way to pass information to and fro, will be for each family to PM us your relevant details:

Real names, cabin numbers, and an e-mail contact. I'll make up a spreadsheet containing all of this information, and at a date to be determined by the group, can e-mail this out. This way everyone will have all of the necessary information of who / where to deliver to during our cruise.
*Perhaps if you plan on seeking an upgrade at the port, you may want to mention this as well, and we can figure out a way of notifying the group if the upgrade is successful.
We prefer to leave the delivery date of FE gifts up to the participating family. That way, this can be done at your leisure, when it is most convenient for you.
The DW likes to by little gifts / trinkets from the area where we are from.

Little trinkets from our local museum, candy made at a local business, things of that nature.
Like Tink rules mentions, this is a lot of fun. Our 2x DS's

love coming back to the cabin, and collecting new booty.
