Thanks for the heads up. I've done private tours at Universal and they were very easy going. The location order was definitely dictated but the guides were very malleable. I'll see what I end up doing. $70 for event ticket and express is dirt cheap. I know in 2009 it wasn't necessary, but in 2011 I wish I would have had it to re-visit houses.I was told by our guide that those tours can be a little crowded and you are at the mercy of the group, if they do a lot of bathroom breaks, drink breaks, or just a bunch of slow pokes. Just a little heads up.
