My husband and I are interested in traveling to the UK in late spring or late summer/early fall 2015. We are senior citizens in good health. We are not interested in taking package tours where we are part of a group of 40 Americans getting a sanitized version of the country. We plan to fly from the US to London and spend 3 days there before flying or taking a train to Edinburgh. We would like to have only 2 or 3 bases while in Scotland for our 10 days there. We hate packing up and moving constantly. We would prefer to get to know fewer places on a more intimate level. A series of day trips from our base would be fine. We are primarily interested in fantastic scenery and history/art. We are not into difficult hiking/climbing but some 6-10 mile walks would be fine. I would love to see some of the isles. Since we've never been to Scotland and most likely will not get back (there are other bucket list items), what are some suggested places to see? We are not interested in trying to cram in the maximum in a short time. Should we rent a car? Public transport? Should we take some 1-2 day trips with local companies like Timberbush or Rabbie's? We want to be economical but it's also a drag to keep your head buried in a guide book or a road map when a guide can save you time and enrich the experience. Also, what is acceptable dress in the cities vs the countryside? We want to pack essentials and not be weighed down with stuff we won't use. Thanks for any help you can offer.
