For cruise ship passengers, business person's lay-overs, or just regular tourists, I provide not only the above-cited tours, but can be leant on for any and all sorts of tourism-related services and counsel.
The fare cited is for up to 4 passengers, NOT including ascent-tickets to the two major sites, and other such extra-costs: US$89 per hour (minimum 5 hours) for my services and BULLET PROOF transport;
or US$39 per hour (minimum 5 hours) for tour-guide-only services.
