I don't know if he is on the Wonder now, but he was our server for our Palo dinner on the Wonder in October 2009. We had such a wonderful dinner experience there with him! I hope you can locate him!
There is a Head Server on the Dream named Dragan, he's from Croatia. He mentioned that he came from the Wonder and was once in Palo. Person you are looking for maybe?
We were on the Wonder to Alaska May 24, 2011.
He was the head server in Palo at that time.
