1. London of course! It really is a GREAT city, Love it! You need at least 5 days and that is going all day every day to take it all in: Big Ben, House of Parliament, London Bridge, the Tower, China Town, Buckingham Palace, British Museum and just simply walking around and pub crawling.
2. Bath. Gorgeous gorgeous town, great shopping and walking around
3. Stonehenge. Hint: there are only 4 nights a year you can actually go beyond the ropes and touch the stones so be sure to go then: Winter/Summer Solstice and the Spring/Autumn Equinox
4. Windsor and Ascot and the surrounding country side area
5. PUBS old old PUBS, gorgeous interiors, history and crazy old
