We did the picante catamaran and really enjoyed it. The crew was great and will pose for pictures. The water was a bit rough and the viewing not so good. That isn't their fault, it was the weather.
Afterwards we thought we'd do some shopping in Zihuatanejo and a bathroom break. You have to pay for that and they ration the paper. None of the merchants were willing to change their prices and most of the stuff you can get in the US and just paint the name on it.
A friend was drinking in one of the areas and tried to pay with his credit card. They only accept cash so keep that in mind. He tended bar for a hour to pay his tab.
It is because of the fishing village that I give it a 3. We didn't make it to Ixtapa. However, friends did hire a cab for a set price to take them to the island and back. The cab decided to take them more places and wouldn't listen to them when they said no. He stopped 3 blocks from the pier and told them the cost was $70, much more then the $17 agreed on. They eventually agreed on $35 as that's all the cash they had on them.
