Sadly, my wife and I had to cancel our biennial visit to Britain this year due to personal reasons and now are considering the best time in 2012 to visit. Normally we come in spring, April/May, or late summer, August/September.
We will spend almost no time in London this trip, concentrating on the Southeast, and travel across southern England and up to Wales (we normally stay for 4 weeks) but I'm concerned about the Summer Olympics and how that will affect travel, pre/post Olympics.
I would think that post Olympics would be a better bet but I might be unaware or overlook something that would affect travel (other than the damn miserable exchange rate that’s giving me a heart attack every time I check it!!!)
So, once again I turn to the TA experts for your opinions and advice
