You don't say how long you are cruising for - this is on the Princess website

Well this looked OK when I copied and pasted it but it looks all muddled now basically formal nights for 3-6 days is 1 7-13 days is 2 14-20 is 3 21-28 is 4 and 29 days + is 5 minimum - the other figures are smart casual evenings .
Thank you from loads of us.
Thank you Pilgrim - extremely helpful. We are on a 12 night cruise so that will be great. A recent P & O cruise of 12 nights had 4 formal evenings, 4 semi-formal requiring jackets and ties for men and the remainder smart casual. The American way is clearly less formal than the British! thanks.
