Hi, Scooby. Sorry, I've been working tonight, hence the late reply.
OK, we booked the flights separately. We booked with RyanAir from Bristol airport (we live three miles away), and it only cost £201 return for the three of us. So, with the tent hire, the whole thing was £286.00.
I think the toilets will be elsewhere, but for that money I'm happy to go in a bucket outside
SelectCamp are a Dutch based company, I believe. The Dutch are soooooo good at this sort of thing, and the recommendation came from Custardo. Now there's a gal who knows her onions.
We're flying to Milan/Bergarmo and hiring a car. That will be an additional cost of £150 (in the region of), but we've got a few months to look for a cheap deal ... and then, of course, there's the spending money because it's all self-catering.
Any way, sorry for the long post, but I think you'll find it's cheaper than a week in Guernsey, all things considered.
