Fascinating thread!! My husband and I have started saving for a projected world cruise to celebrate our retirements, hopefully in the 2027 World Cruise season. We'll see if we make it or not.
Actually, as a Lutheran Pastor, my husband really wanted to hit the Holy Lands on a world cruise. I said, "Wouldn't it make more sense to visit there while you're still in the church so you can come back and use your experiences in your preaching, than after you retire?" Thus we're doing an 11-day Greek Isles cruise in August where we'll hit Jerusalem/Nazareth and other sites in John's ministries. Looking forward to that.
Also saw some interesting cruises on HAL's schedule in the past of fully circling South America or Africa out of Fort Lauderdale, Florida. Something else I'd like to try.
