Panama City, Panama
Our guide was somewhat inexperienced - not saying he was bad, but he was young and really did not provide much information that could have not been read in the museum. We did not feel like we saw much of the city. $60 for the tour is an overkill - take a taxi to all destinations, especially if your party is more than one - taxi is very cheap in Panama - you can get anywhere within tour's reach for $3. You will save time and money and will not lose on quality.
