Bill - Yes Late March might not be the best, but it was a date that was suggested in a previous thread, it can be moved if enough want to.
Kington could be done on the Saturday, Its further up I think its 90 minutes from the accomodation, Sean will know better, the accomodation is very close to the M5, Painswick and Minch in one day is very easy. I dont know the weekend green fee at Kington but its not crazy. Alternatively add Kington to Thursday or Monday.
The accomdation if we get 4 will be a cottage, if we get 12 or close too, its a 7 room, 12 bed lodge with Sky TV, its on a little 9 hole course so theres a bar and some good pubs.
