Sorry, you misunderstood. When you book a cruise, your expectation is to get everything (including hotel stays before or after the cruise, along with flights to and from it) as a single package provided by the cruise vendor (or a travel agency). So the "reservation system" must take care of all of that. When I said "4-5 different websites" I was trying to explain the point that a 60 yo high-income guy is usually not interested in getting the cruise itself on Carnival.com, then go look for excursions on CarribeansExcursion.net and to book flights on Lufthansa.de or AirFrance.fr. It was a remark on the way the Cruise business works, and why it is so, not about architecture. (But, once again, I really believe that we are way off topic... personally I do not really feel like creating a "Ask HN: are microservices a good choice for the cruise industry?" but if someone feels like submitting one I will try to contribute).
