Excellent idea to have air conditioned coach. Excellent idea to have tour guide with loudspeakers on coach. Your tour guide knew his history, spoke with authority, and was obviously enthusiastic about the subject matter! Your tour guide asked if any person had a particular site they may want to see, he showed us the Irish Memorial which we had forgotten existed it moved us to tears when we saw it, also moved Australian tourists as well! Liked the way we had time to reflect when we visited the WW1 memorials and graves the enormity of the death toll requires a little time to absorb. Good lunch served without much time lost. Really good educational day, hard work to remember all, but that's what we came for!
We were able to visit the main points of interest in good time and with good explanations of the sites. Quality learning time was lost during coach travels due to absence of guide microphone and loud speakers over seats. Coach did not have AC so travel was uncomfortable in the hot climate during the trip. Tour guide was thorough in his explanations, but as he was a French National, we had to listen close to understand his good English. Tour guide was courteous to us all.
