Quick post from ECG. Whilst I would never want to compare with other conferences I would like to say that this place has the following lovely features!
A four star hotel (with chandeliers, room service, free wireless, lovely staff and those doors that Josh Lyman can't make work!)
A very new conference centre, with staff who set up rooms EXACTLY as you asked!
Shops (like all the ones you need for creating prayer rooms) within two minutes walk.
We're still getting in the swing of things, but so far so good! (although do pray that my back makes it! Its pretty bad!)
