OK guys - I'll have a better idea of costs after this weekend. But it won't be much at all for accom, mostly it'll just be food/beer/bait and the cost of getting over there. Flying's an option but you need to get there early and so if you've got more gear than they can take on the flight you're on, they just get it across whenever there's extra room and at no extra cost. Otherwise the ferry is a lot longer but you can take more gear and have a few beers which isn't always a bad thing ;)
If those of you who are interested in coming could let me know what weekends you definitely can/can't do between now and Xmas that would be really helpful.
I'm catching up with my cuz on Sat so should be able to get something figured out before we get through too many beers

Cheers fellas
PS I'll definitely be using a sick day or two for this trip - that's what they're for aren't they??
