I have started researching a trip to the UK for 2 weeks in April, 2014, and could use some help figuring out what is feasible. It will be me, my husband, and 13 yr old son. They've never been, and I was there once, 20+ years ago, for 2 weeks. The idea is start in London, for 3.5 days to hit the major tourist attractions. After that, there are several nearby things we would like to see: Windsor and the Harry Potter tour. And then farther out: Avebury, Stonehenge, Bath. And then heading north, Stafford-Upon-Avon, Warwick Castle, Chats worth (maybe).
