You can arrive any time you want. We're not going to be there to set up stuff until lunch/early afternoon. The meet itself will probably really start late afternoon/early evening. I can picture Friday night as people setting up, meeting other people, cooking, messing about and such.
I would imagine that Sat and Sun will be the real get stuck in days. The classroom area has gas lighting so people can collect there. We will also have 2 chutes up so people can get together there.
There will be plenty of space for sorting your accommodation out so there is no rush there. Come, take it easy and get as much out of the weekend as you all want :biggthump
If anyone has specific questions then put them up, I expect that they would benefit all
Cheers
