The part about coming into ports that not many of us like is being bombarded by all the people trying to sell you services, a taxi ride, a tour, drinks, overpriced trinkets... etc etc. We learned to look the other way, and NEVER EVER ask questions about their goods.
Usually when Hayden and I take trips into ports, we like to rent a car, drive OUT of the touristy parts of the city, and see some authentic parts of the country. Stop somewhere and have food at a local place, or try to hit a "memorable location" while there (thanks to Wikipedia). When traveling with a party of 8 people, however, it makes doing just such things, a bit more tricky.
