I did this for my DS5 when we stayed at the Poly last October (not concierge). But, I did the baskets myself. I don't know if that's an option for you. I put all my stuff together for each basket in one suitcase, and then while my parents showed my son the pool and such, my DS and I went ahead to the room and placed the stuff in the basket and set it out on the bed. He was absolutely thrilled, and thought Mickey had put it there for him. (I actually did one for each day we were there based upon which park we would be visiting, and he loved it--he thought Mickey must have told Peter Pan where he was staying.) The arrival basket had a Pal Mickey (which I was fortunate enough to have picked up for me by a friend who went earlier in the summer), an autograph book/fat pen, guest of honor badge, monogrammed Mickey ears, cookies and candies, and a note from Mickey stating that he'd been waiting on him to arrive. Maybe you could do something like that? (My AKL day basket had a Simba and binoculars, etc., my MGM day had Star Wars stuff, my other MK day had Peter Pan PJs and figures as we did the Family Magic Tour, which I highly recommend.) These baskets and the look on my son's face was one of the highlights of our trip!
