We had the lovely Nicola with a car last time who brought herself and a box of Bananas. That meant we could do grocery shopping trips. I think everyone else took a day pack with what ever they needed to get through weekend and either cycled or took the train down. We also did a team load of washing one night. I personally packed very light with a single set of inside clothes, flip flops, minimal set of toiletries, change of cycling gear and a few gels/energy bars in a day pack and cycled down. We ate lunch both sat and Sun at pub/cafe, do dinner yourself Friday (i had takeaways with some others) and we brought groceries and cooked in on sat night. We had the hostel breakfast last time. Bikes were in a locked shed. People peeled off at different times but most of us got a train together to go home.
