So sorry for your loss. I lost my husband in December and did my first solo cruise in August. It was a trip we had planned together for a 50th wedding anniversary. I promised him I would go and I did and I was also brave enough to wonder around Germany, Belgium and Southampton by myself. It was a wonderful trip. I met wonderful people that made this 23 journey so much easier. The hardest part of the trip was getting on the ship and when I had his burial at sea.
It was such a wonderful trip that I have booked another long sailing for next year.
Get on the ship, make new friends, have a wonderful time.
