The merch at the Disney Stores are different from at WDW. I can't say that the WDW stuff is better, just different. It is true that the store merch says "
Disney Store" on it and the WDW stuff says WDW. I guess it depends how detail oriented your family is!

I'm sure the kids won't notice, but you never know abt the parents. You CAN get cute things at WDW for a decent price. The little movie character playsets are adorable and only $12 a piece. We got my DD3 the Sleeping Beauty set. It came with little plastic figurines of Aurora, the Prince, Malificent, the fairies and the spinning wheel. They had sets for just abt every Disney movie you can imagine. I wish I had picked up a couple more for Easter/bday gifts. ANd the smaller stuffed plush toys are not too bad. I think abt $9-$12 each. The Minnie Mouse plush toys dressed as the princesses that they have now are adorable! They also have Mickeys dressed as different characters (jedi, Jack SParrow, etc.). I think I would go with the WDW merch in case the parents are nitpicky, but get each kid a smaller gift to save on $$. HAPPY SHOPPING!!!!
