7 pm is fine chaps
When you do the map of the cruise, it might be an idea to have a couple of stops en route, so that if people get left behind (which will inevitably happen like last time!! Loius & others!) they know where they could catch up. So if there are a couple of places along the way where we could all stop for a bit it would allow others to catch up. IIRC it will probably me ctrying to catch Limiter while he drives through London at breakneck speeds!!
