Shore Excursions?-Panama Canal Cruise

We are booked on Celebrity Infinity's Panama Canal cruise-March 28th. We are interested in seeing the highlights/overview of each port and we need shore excursion recommendations, please, for the following ports:

(1)George Town,Grand Cayman (2)Cartagena, Columbia (3)Puntarenas,Costa Rica (4)Huatulco,Mexico (5)Acapulco,Mexico and (6)Cabo San Lucas,Mexico. Time got away from us--so thank you for your help!

Georgetown and Cartagena you can get good sightseeing tours at the pier. Look for the representatives holding the tour signs. Puntarenas - I recommend Okey Dokey Tours. Look at the tours for Puntarenas on the web site keeping in mind Charlie will modify any of them. We used this company in Limon last year and had a great tour. We booked with Charlie again for our April visit to Puntarenas. Our last visit in Acapulco, we got a taxi tour which we found at the pier. The driver planned our stops to coordinate with the divers' times and gave us a good tour of the area.

We had a fabulous experience with Ricky that we arranged through rickyricardotours.com -- a boat ride down the Tarcoles River. Crocodiles, birds, wonderful guides. All totally positive.
