There are many people at the pier trying to see you excursions, and a polite "no thank you" really seemed to only invite more conversation from them - they were aggressive and didn't leave you alone.
The port part of this town is really a made-up port. A hurricane wrecked the area several years ago, and the rebuilding is at a snail's pace. There is a tourist-only section of shops set up adjacent to the pier with mexican-style souveniers.
Other than going to the beach, it really wasn't worth getting off the ship at this port.
We have been to this port before to go diving, and other than another diving excursion, I don't think we would want to come back to this port.
Our Stingray City encounter was cancelled because of rough water, so just beware that this is a possibility if you book this excursion. Singray city is on the north side of the island, and the cruise port is on the south side, so you can't tell just by how the water looks when you tender in what the water on the opposite side of the island will be like. This was a big disappointment for us.
We were hoping to see monkeys or slots or birds or even butterflies on this tour, but we did not. Turns out, they don't like tourists very much, and by mid day when you get to the tram, it's often hot and they are off sleeping somewhere. The rainforest canopy was neat, especially if you like plants. Big, big, plants.
It was okay, but we would not do it again. Many said that the Puntarenas side of Costa Rica was much better.
