We were on the Dream Aug 2011 with Donnie Osmond. I didn't notice him, but my husband did! Donnie was helping a kid who fell on the stairs while going up to the Aqua Duck (spelling?). My DH kept saying 'I think that's Donnie Osmond!" (quietly), and of course I was oblivious. We found out the next day he had an informal signing for guests, then I got the "told you so" from DH!!
