re clubs >
luxury hotels primarily in asia, some brands only have club in asia
outside asia primarily nonluxury hotels

why in asia, (much) lower costs and demand from business travelers

re ritz carlton not all of them have club, there is new reserve/residence/etc

re including things, there are independent ultra luxury properties that include everything. (names of such properties do NOT include "all-inclusive") sometimes these properties operate at a loss regardless of high rates.
