I went off to Orlando armed with this same list - it's not particularly helpful as it is based on Orlando City rather than WDW (But better than nothing, I'm not complaining)
I went to Stamp your art out - which is near the Florida Mall. If you are into Stamps then it's pretty amazing. They had about 1/4 of the shop dedicatd to Scrapbooking, and had lot's of stickers, paper, albums etc. I wasn't really sure what I was looking for (my first trip to a scrapbooking store), and bought some templates and paper that I don't think I will use, but if you aren't a novice like me then it's probably pretty good.
There is also a Michael's near the top of I-drive - it's just of I4 and was very close to our hotel. We went there a couple of times and I bought quite a lot of stuff from there. I guess you are all familiar with Michaels, but it was new to me (we don't have such a thing as a craft store in the UK) and I was pretty amazed with it.
I also bought a few bits and pieces in the Walmart.
I like the look of the memories website, and I wish we had visited there, but it's not in the 'tourist' area of Orlando, it's in the city.
