Regent Seven Seas Cruises is increasing fares on some of its 2013 voyages from April 1 after seeing strong bookings over the past six months.
Graham Sadler, managing director UK, Europe and Middle East, said the price increase would send a clear message to agents and clients that it is committed to offering the lowest prices to early bookers.
However, many cruises will remain at the same price, it said, and a small number of sailings will go on special offer.
"Every year there will always be a handful of sailings that need a little help, predominantly due to reasons out of our control," added Sadler.
