It is a long 2 days no matter how you do it.
I found it tiring but in a good way ...we got to see most of the main sights but time was cut short by a couple of ladies on the bus that insisted in wandering off at each stop then we had to wait 10-15 while the guide went to find them. Smaller tours are better with 8 people you can remember who was on your tour & drag them back
