Interesting. Seems to be a pattern with higher end hotels/resorts.
One potential theory: is it because people who have the means to afford such level of hotels/resorts...are also more likely to use travel agents/assistants/other personnel to make these bookings and they are not as likely to do it DIY?
Seems like alot of those websites are really "artsy" and are trying to sell an experience/emotion rather than hit you with tons of facts...
