Spot is amazing, and he's been doing it every year for several now. He'll get your pics up, but keep in mind he took hundreds of pictures over the course of the weekend (I know my shoots were each at least 10+ minutes). That's a LOT to sift through! If I recall correctly, last year he started sending them out about a month after con (some a few weeks later). I'm sure the poor guy's got a day job too
We're really fortunate to have someone come and dedicate the time (the entire weekend, including some LATE nights!) to give us some great shots. You'll get lots of pictures (excellent ones, at that), so it's well worth the wait, I assure you
And at the price of FREE, I'd wait several months to get my pics if necessary
