Review: Luxury UK Tour, Scotland, England, London, Edinburgh, York, Stonehenge, Roman Baths, Westminster Abbey, Windsor Castle

The few things we would do differently are:  

Don't pick up a rental car inside the city of London during rush hour morning traffic.  Neither of us had driven in the UK and the rental agency just hand you the keys.  I recommend paying a little more to have the cab take you to the outskirts of town to a rental lot or at least wait until 10:00 so the rush hour is clear.  

We also didn't get any value from the Garmin GPS device.  We had 11:00 passes for Stonehenge without directions. It couldn't get a signal in the city so it was of no use in London even walking around and it wasn't helpful once we did get a signal 5-10 miles outside the city.  We found our IPhones with google maps were more helpful and provided specific directions for the roundabouts.  The Garmin device hadn't been updated in over a year.  Unfortunately we planned to use the Garmin so didn't think to bring a car charger for our phones so we had to be careful and only turn one on at a time as we had a lot of traveling the first day with the car.

We would not have taken the day long bus tour from Edinburgh to southern Scotland.  Although the country side was beautiful and we enjoyed the visit to the ruins, we do not enjoy being stuck on a bus.  More than half of the passengers had a deep continual cough / blowing their nose.  The bus stopped several times so we could get off and wander about, however, we spent about 4+ of the eight hours with people coughing on us.
