I did not get any responses for quite some time - The prices would have been a bit much for us. So, I started to research and found out that It's pretty easy to visit certain places without the tours.
Innitially, the tours I found would pretty much fly through all the different sites/areas - Leaving little time to enjoy.
So, we chose a main place for each stop and a secondary place. We will visit the main place with plenty of time to enjoy; if time permits, we will visit the secondary place of interest.
Good luck with your tours - Hope to see you and your friends there...
