The wife and I are going to the UK for 10 days in March and I'm starting to plan the trip. So far I've bought tickets to London and that's it. We'd like to spend 1 or 2 days in London maybe 2 to 3 days in Cotswold and also spend a few days in Ireland or Scotland. The wife is mostly interested in seeing the countryside, castles and drinking tea. To the English folk around here, would you suggest Ireland or Scotland and why? What other places are a must see?
