Three couples in our fifties traveling to Ireland July 2015 wanting to stop in Scotland for four days/three nights. Husbands hoping to go to British Open at least one day, so exploring options and just beginning to plan. Assume accommodations in St. Andrews limited and pricey due to event, so considering staying in Edinburgh. Would appreciate your thoughts as to places to stay in either locale or points in between as well as how to make the most of our trip and see the wonders of Scotland. Open to hotel (3 to 4 star) or private accommodations, but think if we stay in Edinburgh, we could rely on public transit and not have to rent vehicle for 6 persons. Plans are preliminary so appreciate your input and knowledge of Scotland. Thank you.
