MereMin - This hotel has no Astor Floor as all the Floors are in effect Astor Floors because Butler Service is available to all. For example, the DC St. Regis and I believe some others offer part-time butler service to a designated Astor Floor and to all Suites. The defination of Astor Floors varies between hotels. A few St. Regis hotels have an Astor Floor Lounge, most do not.
Fly CO To See The Yanks - I see your point, however, I think what is happening is much better than in the past. In the past only Astor Suites (when, if ever they updgraded someone) were available for upgrades and everything else was excluded.
