We booked a full day, private van tour from experienced Tours through Viator. This proved to be a very wise decision. Barney, our guide was waiting for us when we got off the tender. His new Mercedes van was comfortable and roomy and easily accommodated our party of 5 adults. Barney had water and snacks available. Barney was a good story teller with an excellent sense of humor, and had an in depth knowledge of history, economy, politics and just about anything we would ask. In his van we were able to drive through and see areas where large busses couldn’t go. Several sites were closed due to the Kings visit, but we did get to see his motorcade . Our entry to the castle was through an express lane with tickets arranged by Experienced Tours. Our last stop was lunch at a pub/inn where some public house has been in existence since the 1300’s. We even got to sit in the same chair the Queen used when she dined here several years ago. In spite of rain and detoured roads, Barney got us back to tender location on time. Several days after this tour, I asked our twin 18 year olds what their favorite part of the cruise was so far. Both enthusiastically exclaimed Barney!!” I would book with Experienced Tours and ask for Barney again.
