So sorry for your loss! My husband died in Nov of 2020 and I have been cruising solo ever since, including four transatlantics. My experience is that there were always quite a lot of solo travellers on each of these cruises, some were widowers/widows, some were leaving their partners at home for various reasons, but one thing all solos had/have in common....... everybody just loves to cruise! The above post from #leaveitallbehind is good advice. Find your roll call for the cruise you are interested in, sign up and you'll connect with other solos. Anne
