1. Has anyone purchased Disney luggage, like Minnie or Mickey, for themselves (adults) for travel or has it been primarily for the kids?
I've bought it for myself.
2. If yes for the adults, did you get a set or just select pieces? If pieces, what size?
I've had a couple of different ones. Carryon size. Will explain below.
Are there a lot of Disney luggage coming off the baggage claims ramps?
No. And that's one of the reasons I buy stuff like that. Very visible, doesn't look expensive. So the first prevents accidental grabbing, second prevent active thieving. Harder to get away with and I would think they'd be more likely to go for visibly expensive stuff- tumi, Louis Vuitton- because thieves are usually after contents rather than bags.
I'm a little concerned that having that high of a profile luggage, instead of the usual solid black luggage, might attract someone to take. Should I worry? Nope, see above.
And then, on the other hand, how uber cool it is to have unique luggage and something that is to spot when it comes off the ramps!
Yes!
*I've only had carryon type stuff because the trouble with novelty stuff, like character suitcases or whatever, is that it's usually cheap crap and missing key components that I want in a suitcase like good wheels, quality pockets and straps.
And I haven't seen the luggage equivalent of Disney coach or Dooney and Burke. I would look at your familiar brands for special editions first if you want a suitcase that will last and you're a frequent traveller.
Mostly I've settled for awesome kid luggage tags, because I don't like replacing stuff. Like think red samsonite or victrinox with Minnie tags and a polka dot band or something.
