I agree about coffee in the lobby not being acceptable. I don't even want my husband to see me before I have my morning coffee! And he hates going downstairs and getting my coffee for me.
FWIW - this is the coffee maker we found at the Hilton in Gainesville FL (typical Hilton - not a luxury property) last fall:

Was really nice for 2 people. Robyn
