I sold Disney tickets on Ebay. Heck, when Hotwire Savings Club was up and running I made at least $50 on each ticket in general. We are not even going to talk about the many meal vouchers I sold. I even sold Disney tickets that were used - I was upfront and said that the tickets were originally 5 day hoppers that were used for only one day or so. All of my tickets have been legit. Now, I wouldn't buy tickets from a new seller and I wouldn't buy tickets too far in advanced. Within 60 days of your trip. That way if something does happen it is retractable - especially if done through a big bank. Read the sellers feedback, and look at all the items they are selling. If they have 100's of tickets - unless they are a company - yes they may be trying to get over. Read your auction carefully. There are many people with extra childs tickets - I am one of them. Because I am a family of 3 I have one extra childs tickets. I will possibly sell them online. My SIL (a family of 5) has two extra childs tickets because she has one son who is 11 and one is 8 and a baby girl who is 1, so she had to buy 3 adult tickets.
