Couple of points re photos:
The offer applies to each member, and not cabin, so don't assume like I did that it was only one free per cabin.
Also, If you don't want a personal pic, the pictures of the ship itself are included in the offer, and make a lovely addition to my cruise folder, containing Cruise Compass, etc.
Both a bit obvious I know, but this idiot (me) missed out on a couple of cruises before he realised 😁
