Hi Duncan,
I think a lot of people are doing the same these days and having a weekend off after being out the previous week due to the costs involved with the hobby. I did enjoy the day out, as we couldn't go for the weekend this year, and we will more than likely be back again next year. I'm not sure about the dates as this year I know it had to be slotted in after Belvoir was no longer available. Whether it will revert back to the old dates of the third weekend in May I do not know.
