Don't forget that the Concord Room doesn't open until 06:00 (?) so don't get there too early!
Book an Elemis treatment as soon as you get to the CCR. IMHO totally ignore the BAA mall unless you "really" are bored!
Make significant inroads in the Bolly supply in the CCR and generally pig out!
Enjoy the relaxed feeling of doing it on your own time and dollar!
