It wasn't really that messy, but can see possibilities. We has around 30 people including 5 kids. Nobody got any on them. They put the chocolate in those warming things (sorry the exact word is escaping me at the moment). The stuff they use to put food out on a buffet. Anyways, they had dark and white chocolate for dipping. They had all the dipping stuff (fruits, marshmallows, pretzels, etc.) next to it. They had wooden skewers you could use to dip the items. It was pretty easy except for all the people around it trying to get some. For your non dairy/nut stuff, Disney will easily work with you on it. I really enjoyed the station and would highly recommend it.
