I used to have a time share for such a situation but I got rid of it and become more of a stay at home man.
Can't stand all the security at airports it makes the first and last day of my holidays a pain. Particularly the day I come back it can add a bit of an anti- climax to the holiday.
But that's me!
Regarding you setting the classes for the next show I have attached a show schedule that might help you with your 'picking'
When it comes to the judging let me give you a friendly word of advice and that is........
Your parentage is going to come into question
We have a few people on the plot who have their holiday homes and are away for months at a time then they wonder why they can't grow good stuff (apart from weeds)
But. I wish you well....as they say: each to their own
Here is the schedule
