Please share your experiences on what you would consider doing for two days prior to beginning the tour in Bath in September.
Stonehenge.
When i went on the ETBD in 2009 i flew into London 2 days early. Saw a few museums there not included on the tour like the British Museum and the V&A. We also went to Stonehenge on a free afternoon during the tour while we were staying in Bath. At the end of the tour we added a few days and went to Edinburgh. All were great additions.
