Panama City is such a huge place we thought the best way to get the overview would be the Hop On Hop Off bus. The down side was they only had 2 buses running the 16 stop route and there was a ton of traffic everywhere due to the holidays and the wait time at spots was really long with an app that did not give accurate info. Regardless a lot of other fellow residents had the same idea - so our core group of 8 was constantly fluctuating. 

Scott & I jumped off bus at Panama Canal Museum. They had an excellent IMAX movie on the history of the Canal narrated by Morgan Freeman - we had a lot of laughs, as we tried to see IMAX over 3 intervals - last 1/2 - first 1/3 then somewhere in middle - whille we tried to catch the next buses on route. After 2 failed attempts we took a taxi to Old City. We did get a nice Air Conditioning break, restrooms and cold beverages. Did I say it was stinking HOT with really uncomfortable seats on the HOHO Bus!?!
