In reply to georgiaaharriet:
No idea what you have in mind, and who will comprise your group, but the Borrowdale Youth Hostel allow camping in their grounds for a reasonable price (£10 per person per night) - for that you get access to their bar, common room and facilities - a good place to retreat to if the weather is bad.
If car camping then throw in some extra blankets etc, just in case it is cold at night.
