We have the Mayan Ruins on our list of places to see. The Chichen Itza ruins were well worth the 2 hour long bus ride to the site, and the over 100 degree weather once there.
The tour was booked through HAL, and as the bus could not handle the heat, they changed buses for the ride back, which was very appreciated by all.
The site was very crowded with tours, which made staying with our guide a challenge and we ended up going off on our own. The only issue was the lack of time to stay at the site, as your spend 3 to 4 hours in travel to and from. We need to go back for another visit.
WE also stopped at Paraiso (Tabasco) the previous day, and went to see the Comalcalco Mayan Ruins and Paraios town. The ruins are a good as Chichen Itza, though different and well worth the visit.
Cartagena, Columbia was a very pleasant experience, though we were only in port for 1/2 day. I did not have any expectations when we arrived but the tour was excellent. There was a presense of police, but nothing offensive or too much, just enough to make the tourist feel safer. Drive to sites were clean and saw tourists walking around.
We took a HAL tour 'scenes of Cartagena with less shopping', as I am not a shopper, but we like museums and history sites. Our guide spoke very good English and was very knowledgeable.
The highlight for me was the section of the city that has been restored/maintained as it was-Old Town streets are cobblestone and narrow. The San Felipe de Barajas Fort, and Navy Museum were also very worthwhile seeing.
We took a HAL excursion 'Countryside and coffee tour' Tour was a 1 hour bus ride each way through countryside on PAN AM highway. The bus ride was interesting as the road is two lane and many big trucks travel on it up and down and around corners.
We went to a co-op coffee plantation which showed all stages of the process which was interesting. The site is over 600 acres and some of the owners live around the site in small houses. They were not working the site where we could see, but guides walked us around some of the area and showed us the process (before and now). Guides split group up into smaller groups so make the tour more interesting for everyone, as all the questions and answers could be heard.
We also had a brief stop at a shopping site which had a very nice lunch counter, with lots of tourists and local customers. Felt that the area is very safe for tourists.
Antigua is the colonial capital and has retained a lot of the historical look of the town. We took a cruise ship organized tour: Past and present colonial Antigua, which meant a 90 min. drive each way from the port Puerto Quetzal, which was very scenic through the countryside.
Big buses have great difficulty getting around Antigua and therefore I recommend small van tour rather than big bus due to difficulty. There were a number of times that it took minutes to turn a corner or get past another vehicle once near Antigua with a big bus.
Cabo San Lucas is very tourist friendly, whether on an excursion from the cruise ship or on your own, we found. On a previous cruise we had taken 'coastal highlights which gives a real good flavor for area' so did not take a tour this time.
As the ship docks, and then tenders are taken to shore, there is a long boardwalk with restaurants and shops within easy walking distance to enjoy, which we did. It also helped that security was located every few feet to make sure the vendors stayed off the main walking path, which make our stroll more enjoyable. There are also a number of water taxis available at a reasonable price if you want to go for a short tour.
Acapulco has only one great thing to see and that is the cliff divers, which are something everyone should see at least once in their lifetime. Other than that it is a big city, which has great picture taking opportunities as you sail into or our of the port.
We had seen the divers before, so we decided to go to the Museo Historico de Acapulco, which is an easy walk from the ship dock. In fact, you can see it on the hill across the street. For those with limited mobility, there is an elevator or stairs to take you up the worst part of the climb. Well worth the $4.00 American per person to see. We spent about an hour at the site.
Los Angeles port was actually Long Beach port next to the Queen Mary. Tour was highlights, which meant more time in traffic than seeing anything. Also included a stop at the 'Farmers Market', where locals eat but if the price was anything to go by, the locals would not go every day to eat. Food was good but pricey for lunch.
As Queen Mary is right there next to ship, I would recommend taking some time to tour it, instead of spending a few hours in traffic and crowded streets.
