I've just returned from visiting The Beach House Hotel in Seahouses to check out availability and cost. The only weekend available in April is Friday 4th to Sunday 6th next avaiable date is 2nd to 4th May. Cost would be £50 to £55 for dinner bed and breakfast.
Will someone, with the necessary expertise, please set up a poll so we can vote for either of the two dates that Les has provided, or for neither as a third option. This last will mean that the we will have to find another venue. I would do it, but I haven’t got a clue where to start.
