Thank you for your response. Could you share your private driver information? Here is the description from Celebrity on the one by water. It's the same description just by land on the other excursion:
Experience the spectacular Amalfi Coast from the waters of the Mediterranean onboard a sleek motor launch, then tour the historic ruins of Pompeii. After your cruise, you'll enjoy some time to explore Amalfi's charming narrow streets, trendy boutiques, and local cafes before heading to Pompeii. Once there, break for lunch before exploring the remnants of this city, learning how the catastrophic eruption of the still active Mt. Vesuvius covered Pompeii in ash and pumice.
