You could try any number of search terms. "Walt Disney World pin trading" might work, for instance. Or "disney world pins", or "pin trading", or you could also try character names, like "winnie the pooh pins". If you want to follow a path through "browsing categories" from the main buy page on ebay, try starting in "collectibles" or "toys & hobbies", maybe even "entertainment memorabilia". I've gotten lots of healthy lists using any of those. But I'm more of an ebay window shopper myself. I'm thinking of listing some Disney pins in the coming week. If I think of it, and if it's allowed, I'll, make mention of it here.
