I checked up on Tattoo tickets and it's offical they are sold out - http://www.edinburgh-tattoo.co.uk/news/index.php

Doesn't mean you can't get them from a package however. I would avoid ticket touts offering you tickets when you are there though, they charge ridiculous prices and we have heard of tickets for many events not being genuine.

I am spending a couple of nights in Stirling next month so will no doubt share a few piccies on my return!
