So update:
We decided ultimately not to go with a travel agency and planned everything ourselves. Previous itinerary before this post was what we have decided with the exception of staying in Bath. We are now staying in Exeter.
We are firming up our plans for our 4 days in London among the highlights are a medieval dinner, a hop on hop off bus tour, 221B Baker Street Museum and the changing of the guard. Much more is scheduled and being looked at however so stay tuned.
We have Wifi access each night so I will be updating the blog daily with pictures and stories along the route. I will also post driving routes via google maps. Keep in mind that we are 8 hours ahead.
Not quite excited yet but I'm sure the day of will see us itching to get out of dodge...
