It was a paperback about two girls on a trip with their family and they stop at some mine or cave. The younger sister runs off into the gift shop and the older follows. The evil gift shop owner ends up trapping both in a giant snow globe as pets for a giant family in the cave system. They really just wanted the little sister so the elder is a freebie. They end up escaping when the older girl melts the snow globe on the fireplace or something and they run out through the tunnels. Might have been apple paperbacks or similar.

Yes, that seems very familiar. I think you’re right. Thank you!
