Italy Family Travel Review: Venice, Florence, Amalfi Coast, Rome, Path of the Gods Hike, St Clements Basilica Underground Tour

Our trip to Italy overall was wonderful. We felt we had the right amount of time in each city: Venice, Florence, Amalfi coast and finishing in Rome. The tours we took were all excellent with wonderful guides. We especially liked our guide in Rome. We love the small private tour groups as we feel we get much more insight into the places we travel outside the obvious tourist spots. 
Most trips I've been on have a few small hiccups and how they are managed matters. We were scheduled to do a lace making tour on Burano but our guide did not have this info and we did not get to see this island. While to be totally honest, my kids were fine missing the lace part, we were bummed to miss the colorful houses. 
I don't think I realized that the Amalfi coast was a cruise boat destination and on our arrival day the streets were jam packed with tourists which is something we overall try to avoid. The hotel was right on the main street and was very noisy. Not sure any of us slept much those two nights. In retrospect we would have not chosen Amalfi had we realized this. The Path of the Gods was a fantastic hike and we very much enjoyed that. 
We booked this trip last September and the single tour we as a family were most looking forward to was the underground Colosseum tour. I knew it had very limited spots available and I requested tickets literally 9 months early. We found out at 9pm the night before that we did not have underground tickets. I asked if we could try for the following day, knowing it was a long shot and was told our agent would get back to me "ASAP". We did not hear back for well over 24 hours and not until after 1am the following day that we could not do the tour the following day either. The last day in Rome we missed a 3rd planned tour to see the houses in Celian Hill because we did not have tickets as planned. My kids are 5th year latin students and they were quite disappointed to miss the special underground Rome sites that were saved for the end as a way to cap off our tour. 
The tours we did take were wonderful and the rest of the trip was lovely.
