The first solo bike tour I took was 2 weeks around Southern England on a borrowed bike. I either stayed in Pubs or with family. These days, I'd use couchsurfing.com or warmshowers.org to find people to host me (for free) for the night. While wind and rain are plentiful in the UK, the scenery is very pleasant and it is easy to find low traffic, if circuitous, roads using the AAA road atlas available everywhere. After a subsequent tour, I made the observation that when the wind is at your back, you know you've made a wrong turn.
I wrote a journal of my 2 week tour. You can see it
here.
I've always enjoyed riding in the UK and highly recommend it.
