Emergency School Holiday Plan

I normally save this for a point later in the school summer holidays.  It's the "Emergency School Holiday Plan" which should only be deployed in case of emergencies.
Yesterday was the first day of the holidays that I was spending with Hannah and Ethan.
Last Friday didn't count because a) it was an inset day and b) Hannah spent most of the day at the local horse sanctuary having an "experience".  She was mucking out horses, preparing feed, grooming and generally having a good time and learning about horses (and pigs and goats and....because even though it's a horse sanctuary they do other things too.)
Weekends don't count because they don't and because weekends happen all year; school holidays don't.
Monday to Wednesday didn't count because the children were staying with their grandparents.
So yesterday was our first day together.  And I had an appointment with British Gas in the morning and "Fridgeman" in the afternoon.
Our boiler has been kaput for an age and this was the first time I'd been able to get an appointment on a day when I could be at home during the morning or afternoon.  And our fridge went pop earlier this week so Dave arranged for Fridgeman (nice chap from C & M Domestic Appliances) to pop round and fix the fridge (or try to).
This meant we were tied to the house and, after a DVD morning, the children needed a project.  I resorted to the tried and tested plan without any regard for the consequences: Camping in the garden.
I didn't get the big tents out, just the two man tent that Dave and I used to use.  The project involves putting the tent up, making up beds and ensuring the tent is filled with home comforts and then, the final touch, sleeping in the tent overnight.
I now have nowhere to go.  The Emergency Plan has been deployed and there is nothing left.
