I didn't know that about tickets on the continent not selling so quickly - it's such a difference to the mad rush in the UK when we tried getting them within the first minutes of opening and Katy already tweeting which arenas were already sold out!!
But I hope they will eventually sell out!! - I did read the thread, just don't want to quote nearly everybody again.
Btw, I found that bags in the RS are really relatively safe. And dehydration is only a problem if you refuse to leave 'your' spot, but you'd just stroll out to the grab water and come back at your leisure.
