Just book Carlisle - the event centre at the end is fine - showers, very good food and a nice carpeted area to sleep on. Or you could hit Newcastle for a night clubbing. I stayed at the Holly Tree guest house in Carlisle where he got up to do a pre walk breakfast for about 5 of us staying there. Its a bit of a way from the start but I took a bike and tied it up at the Castle and it was still OK when I got back (got a lift on the event bus) Sunday morning
Some route variants going on at the moment with 29 and 30 following the road and 11 and 96 taking a forest track rather than crossing Hawk Side - longer but I bet its more comfortable in the trees on a good track.
It happens every 3 years and its a fantastic route, great cake and loads of other food as well. Somewhere I have a route description but the memories include a punishing climb out of Lewes over a golf course, (don't be tempted to have pint in the real ale pub first) crossing Wiilingdon Hill towards East Dean walking towards the sea with the sun beginning to set - the section along the 7 Sisters to Cuckmere Haven was if anything even better- and care is needed crossing the railway at Southease in the dark. Just enter - you will get a route description in plenty of time if you want to recce - I just turned up on the day.
