Once you get use to driving in the gutter you'll be OK

As you will be driving alone I would recommend Normandy as a good destination and don't just limit yourself to Yelloh there are quite a few companies selling to the UK you can use -- Matthews , Eurocamp, Keycamp, Canvas OK some are owned by the same parent company but they all charge different prices.

I take it you are planning on using pre erected tents but be aware there are other companies that cater for those of us with our own equipment too and with the price of equipment at places like Halfords it may work out tons cheaper too

if you have any specific questions post away or PM me if you want we are always here
