We are going to be cruising and will be in port at Fuerte Amador from 8:00 AM to 4:00 AM. We want to visit Casco Viejo, Panama La Vieja, Miraflores Locks and the Amador Caueway. I do not know if a hop on hop off bus or taxi would be better. Does anyone know what order we should visit the sits I have listed and do you think we have enough time to do everything? Any suggestions would be greatly appreciated.
