Hello, we are looking for some suggestion for us to plan a 10-day (flights not-included) maiden trip to the U.K. Tentative date is next July. We've got two active 10-year-olds (will be 11 next year), which means they probably wouldn't do museums well but would dig a lot of variety of attractions, the more outdoors the better. We don't have a lot of ideas yet. We certainly want to spend adequate time in London but not too much, and would love to visit the Stonehenge, Oxford or Cambridge, maybe a short trip to Scotland if time permitted. We'd also appreciate some tips in lodging particularly in London. We try to contain our lodging budget to under US$300 per night if possible, definitely under $400.
Thanks in advance
