Find Your Cruise
Why not ask Fred. Olsen Cruise Lines? This usually means that you have to arrange your own flights and transfers which is fairly uncommon for this cruise line.
" Cruise only" means exactly that. The amount you pay will cover the cruise and anything associated with it, excluding extras, after the time of boarding until disembarkation. So getting to the cruise port and home from it will be entirely at your cost. .... Neil.
