The PnL test is clear: this logical opposition between Mathieu and Camille, a party student and a traveler seeking relaxation, is not so simple.
If the business loses, the argument was weak, and here the drawdown would be the missed opportunity to reach both segments.
A clever travel operator can very well sell budget student packages and romantic cruises to different clientele.
The important thing is not that they oppose each other in theory, but how to monetize them in practice, for example, by offering deals for students during university holidays and luxury stays off-season.

PnL test: a claim as categorical as humidity being a decisive comfort factor could risk causing travel agencies to lose money.
If a travel guide discouraged visiting a destination like Lucerne in summer solely because of humidity, without mentioning refreshing alternatives available, it would miss sales.
The impact of humidity is conditional, not universally decisive; an informed tourist can manage this factor with shade, water, or air conditioning.
Take Ticino as an example: it’s hot and humid in summer, but lakeside beaches and grottoes make the heat bearable and even pleasant.
A guide should evaluate the profitability of the customer experience, not just raw data.

Drop the glossy hype and ask: does this really change the game for the average traveler or the cash flow of a company?
A survey on Google Forms, even with 78 responses, does not prove much about the real cause behind document verification.
It is only a descriptive observation, not a solid explanation of why 75% act this way, while for 25% vacation planning is done at the last minute.
For example, in Germany, checking documents is a bureaucratic necessity dictated by compliance, not just a vacation habit.
