We were going to have a long layover in Panama City after a 10 day trip to Peru, and my husband always wanted to see the Panama Canal, so I deliberately chose flights that would provide enough time to take a half-day tour of the city, including the Canal.
Our guide, Miguel, was knowledgeable and flexible, adjusting our tour as needed. He was also thoughtful to my husband's walking limitations. All in all, the tour was exactly what we wanted and expected.
I don't recall receiving and looked but did not find a final summary email of expectations prior to our tour, just an acknowledgement of payment. Such a summary ('Your guide will monitor your flight and meet you outside the baggage claim area with a sign.... etc.') As I usually get such a message, I worried (unnecessarily) that I had perhaps not given the required flight info and, until we actually found the guide exactly where he might be expected, I was a little anxious. This was the tail end of a long, complex trip and I was tired, so having the reassurance of a summary email would have eased my mind.
