Working for Inter.Continental Hotels had it perks at that time. We could get comp rooms for up
to 5 nights anywhere in the world at any IC hotel. And having so much vacation time, up to six
weeks, we made good use of these benefits. Some of the cities we visited (at no cost for
lodging...): San Francisco, San Diego (now the Marriott), Rome, Budapest, New York, Hanover,
Munich (Penta), Luxemburg, Lissabon.
I asked an IHG employee recently if they are still able to book for free and she told me that that was removed a long time ago. We were really lucky then.
