Questing was one of the things my sister and I most looked forward to during our vacations. I'm very grateful we had the opportunity.
I think the guest rooms were my favorite. I was most proud of my invisibility magic. :P I kept most of my furniture, but I traded or gave away any extra hats I had. (:
I
believe I have/had multiples (at least 5 for most) of every card except the Stitch & HM which I wasn't able to get my hands on. Although I wasn't able to do the insider tour, I was given the pirate set (don't remember why) but not HM. Reading through the wiki list, every card said to DLR exclusive was somehow obtainable in WDW. My memory of that is a blur, though.
I took a pic of my cards and posted it on the old forum, but it was then I realized I'm missing over half of my cards. I'm afraid they're still 2,000 miles away and were possibly water damaged or packed away where I'll never find them.
I hope I can find them when I go back this year.
