Cruise Trip Planner and Shore Excursion Optimizer

## CONTEXT
Cruises pack many destinations into one trip, but the format has its own logic that newcomers misjudge. Port days are short, ship excursions are convenient but pricey, and the onboard experience is engineered to extract extra spending. A smart cruise plan optimizes cabin choice, maximizes each port's limited hours, and decides where independent exploration beats booked excursions.
