The Itinerary is very Good, but the pace was grueling with very early starts and long days.
The City Visits tours were very superficial at best missed a lot of the places we visited. Luckily, I had been there before was able to use our Free Time well, so I know a lot was missed.
Our Great European Tour group was shunted among other tour groups and from one guide to another from one bus to another, which came with the other much smaller tour groups we joined. Many of our tour group felt our tour was very compromised by this arrangement and would expect that the Grand Tour would have one guide fewer buses throughout.
Also, some guides were very rigid with times with 1 disabled passenger abandoned in a city because he could not make the curfew return time to the meeting place.
Also the hotels were understandably very remote from town centres in semi industrial settings the bus parking places did restrict access to some attractions in some cities.
Generally a good tour which could have been so much better, is service had been better.
