We are from the Washington, DC area and are planning to bring little "resin boxes" 3" x 1" to give as thank you gifts to the counselors. They have the white house on the top and open to hold rings, change, etc. We thought they were petite enough not to be to cumbersome to them. We are also bringing some extras to put the cash tips into for the other staff. We figured the white house would be something everyone would recognize no matter what country they are from.
