My husband has yet to take a cruise with me & I am not holding my breathe for him to change his mind any time soon. The fool thinks working in his yard beats a trip any day.
I always sail as a single. Hate the single supplement, love having the entire room to myself! My 2nd cruise was a 3 week B2B that included a crossing. I did not know a single person when I boarded. Not a problem. I met people at the muster & it was party time from then on. They always have a cocktail party before dinner on the first night out for singles. If you haven't met anyone after 2 hours on board, be sure to attend this. Instant dinner companions the first night. Also, take an excursion the 1st day. You will make friends doing that.
But with it being 007, you are not going to have any problems. You will already know people & they are already friends.
Relax & enjoy.
