This was such a good deal, GBP299 each including flights that it couldn't be refused! We sailed 17-26th January '13.
Our only previous cruise was with P&O on the Arcadia at about 8 x the price, so not completely fair to make a direct comparison, but I will!
We have not flown Easyjet for many years but I have to say that they were excellent. On time, friendly, allocated seats, clean etc. so perfectly acceptable for a short haul flight.
Beds a bit hard but perhaps we could have asked for a topper. Furniture a bit rickety but we managed! Bathroom very good. Powerful and very spacious shower.
