YES YES YES In your carry on!!!!! Thanks for posting that crucial info!!! Last year Layne had to carry it for me in his carry on and he was responsible for no crinkling of the gift bag!!!
The Promenade Lounge (for the newbies) is a small area in Aft of the ship on deck 3 before you get to Parrot Cay

I will be sitting up at the 'bar area" because it is a central location as you can see by the deck plans and easily visible by all the seating.... SO I will be found on a bar stool

Not in a BAR

Also some examples of previous DIS Meet swaps I have seen sports memorabilia, special candy from areas, tshirts, wind chimes, pottery a variety of stuff!!! Last year I went to a local store and my gift was 2 local made soaps, hand lotion and 2 embrodried wash cloths saying "Mebane"

It is so open to anything you want to give.......

If you have adults in your family that want to buy sep gifts it will be fine!!!!! Everyone who gives a gift will get one!!!! Please trust me on this .... It is easy
