Most of the episodes listed in "Hotel Impossible: 5 Star Secrets" are also listed as special episodes of "Hotel Impossible". http://www.travelchannel.com/shows/hotel-impossible/episodes lists all of these episodes as part of the main "Hotel Impossible" series, although there is some inconsistency as to how these episodes appear in other 3rd party TV listing sites (TV Guide, zap2it, etc.). I can see arguments for either way of listing the episodes, although I don't think it's correct to have a given episode appear in two places in the database.
