Was also on the 1/30-2/3 Wonder and I kept forgetting to drop off my things to be signed. I think I finally dropped them off the 2nd night really late. When I walked up to GS there was noone there. After a half minute a CM walked out and I handed her my sealed zip lock bag. I stated I wanted to drop these off to be signed and she looked and saw that I included a card w/our name and SR# and said ok thanks, you can pick them up the last night of the cruise.
Around 11pm the last night we went to get them and they weren't ready, they said they'd be ready in the morning. So on our way to early breakfast I stopped by and got everything. My zip lock bag contained 2 t shirts, 3 picture frame mats and 2 pillowcases. The shirts only had Mickey and Minnie signatures. They also used the color markers I enclosed.
