The recent Carnival Cruise catastrophe appears to have soured people on cruises in general.  Fifty-seven-percent of all respondents in a new Harris Interactive poll say they believe it's "much more reliable" to fly than to take a cruise, and 50-percent think flying is "much safer."  And overall, just 35-percent feel a cruise is "worry free."  But opinions vary depending on experience.  Among those who've taken a cruise before, 53-percent would describe them as "worry free," compared to just 25-percent of those who haven't ever been on a cruise.  And of the experienced cruise travelers polled, 64-percent feel air travel is less reliable and 55-percent think planes are less safe.  However, even those who've been on a cruise are now thinking twice about future trips.  Forty-three-percent of former cruise travelers admit they're less inclined to take a cruise now than they were a year ago, along with 58-percent of those who've never gone on a cruise. However, even though the early spring to Spokane has brought a great feeling, dreaming about sunshine while on a cruise still feels pretty good.
