Lots of notice this time, good move Richard.
and, yes, I'd certainly be up for a trip to the deep south, where men are men and sheep, well best left to the locals !!
Also, it is best that the Lakes and TitV don't clash, considering Jenny's comment it looks like summer is a preffered time. A year away may sound a long time, but in organisation terms, it's about right!
To assist you, as nothing has been decided yet, I'll propose that the Lakes meet is the same time as last year. Easter 2012 is early April, so we'll aim to fit the Lakes in between 16th April (schools go back) and mid/end May. There are some other events normally run around this time too (Ripley comes to mind) This gives you some dates to play with, I'd suggest trying to keep at least a month between the two events.
As for the TitV, for me the option of a Friday arrival, with a Monday departure would mean maximising the weekend, so there should be some basic facilities available, but I can rough it if needs be. Prefference would be showers, but I'll go with the flow.
Date dependant, I might even mix this up with a road trip around Wales.
