Hey there! We've used them before too, and here's what we did.
First of all, don't worry, there shouldn't be a huge lineup (depends on when you're going, I guess) We had to go to the WILL CALL window, which is separate from the main ticket windows. Both times we went there, there was NO LINE. We went to it the evening before we needed our tickets, right before they were closing. We got our tickets, and didn't activate them until the next morning. (They don't become active until you go through the gate).
It worked out really great for us TWICE and I wouldn't worry too much. It's truly not a hassle. We were worried about that too, but it was such a piece of cake.
Having said that, we did go in the off-season, so again, it may vary depending on season. I think the key though, is the WILL CALL window versus the main ticket windows. It's kinda around the CA side of the ticket booths, and has always looked pretty empty to us.
Sorry you were so disappointed. We were at first too, but then we found out that very few places (except Disney itself) actually send you the tickets, so we figured it was a common thing.
Hope it works out for you!
