That contradicts itself, it says gratuity included as it does on the UK site, so there is no 15% saving by booking prior to a cruise because it has now been included. Shorter cruises attract a higher per day cost. While we have Premium extra included for our next cruise, when I look at the Easy package it works out at £34 per day for 12 nights, someone on a 3 night cruise is paying £111 pp, so £37 per day.
