Judging by the URL structure, this is built on Adobe (formerly Day)'s Communique 5.x platform. The CQ Platform gives you a ton of these graphical widgets and social interaction out of the box, though there is still plenty of development to write a full reservation system. It also handle mobile rendering, site templating, and multiple languages quite well. So while it sounds like people are seeing "a single website for $18m", I'd be willing to wager that was the cost for the entire content platform (CMS/Social/Mailings/Reservation system. So now they would have access to very advanced templating design, multi-lingual components. The amount of time it would take them to roll out multiple country and language sites would be dwarfed in comparison to any other platform. That $18m may be a big upfront costs, but might well pay for itself if they intend to use for other properties and across multiple regions/languages.
