We’ve actually had spinners from the Disney Store, and while the kids liked them, they have yet to ask for another. :huh: But that being said at WDW, parades, 4th of July etc I load my kids up with glow bracelets, etc. Usually Dollar Tree has oooodles and even has wands etc. I just break out a new tube or 2 every night. There are also modified versions of spinners at Target, wal-mart, etc that are a dome on a handle/wand. Inside it there are a bunch of lights, when the button si pressed it lights up, spins, and makes all kinds of patterns etc. Those are generally $10 or less each. I think the main issue w/ the spinners was that my kids had to keep the button pressed, and eventually they got tired of the shaking and thumb ache.
Glow bracelets/necklaces are great to hang on strollers, backpacks, kids, etc. We did this last trip and no one tripped on our stroller, etc.
