Regent Seven Seas Cruises has enacted a stricter cancellation policy for 2011 cruises.

In a letter sent to travel agents on Oct. 30, Regent said that if customers cancel between 91 and 120 days prior to departure, they would pay a 15% penalty. The 15% cancellation fee usually will be higher than the current flat fee of $400.

The penalty climbs to 50% if the cancellation comes within 51 to 90 days prior to departure, up from the current 10% penalty on cruises canceled between 61 and 90 days out.

The penalty jumps to 75% if the cancellation occurs between 31 and 50 days before departure, up from the current 25% if cancellation is between 31 and 60 days.

If customers cancel within 30 days prior to embarkation, they will incur a 100% cancellation penalty. Currently, customers can cancel within 15 to 30 days of the cruise and pay a 50% fee.

Customers still will pay a $200 flat fee if they cancel more than 120 days out.

The report was corrected to state that customers canceling within 30 days prior to sailing will pay a 100% cancellation penalty.
