Have been traveling off and on for a month in various portions of the
U.S. Staying in nice hotels, various Hiltons, Marriotts, Starwood
places and even some which are on the list of "best small luxury
hotels" in the world. NONE of them have mini bars anymore. when did
the mini bars disappear??? I always loved looking in there to see the
tiny bottles, different juices and soft drinks, candies and nuts. 
Sometimes I even bought something when I was desperate, even at the
inflated prices. So it's been sad to see the passing of another era in
the U.S. You can still find them in many hotels in other countries but
will they slowly disappear also? Going the way of the clacking train
schedules in cavernous railroad halls.
The Hilton Bonaventure does have a mini bar with a special key. small favors
