Final answer:
Cruise passengers spending over £85 typically settle a combined bill for all onboard transactions at the end of the cruise; a survey of travelers' expenses may influence payment policies.
Step-by-step explanation:
When a passenger spends over £85 onboard, cruise ships often require the passenger to settle one combined bill at the end of the journey for all onboard transactions.
This system is designed to be cashless, where all expenses except for souvenirs are charged to the passenger's account to streamline the payment process. In the provided scenario, a survey investigated the onboard bills of 60 single travelers and 70 couples on a seven-day cruise from Los Angeles to the Mexican Riviera. The analysis of these bills could reveal spending patterns and determine if additional steps such as deposits or credit card holds are necessary for certain spending thresholds.
