4) Disney tickets for sale on eBay
Tickets for sale on eBay are risky also. Is there a chance you’re bidding on unused tickets that might be valid for use at the gates? Yes. But there’s also a chance you’re being scammed into buying partially-used (invalid) or fake tickets on eBay. It’s not worth the risk, and you won’t know you’ve been scammed until you get to the gates and are turned away.
