I can't imagine a more unforgettable trip and I strongly recommend that you take it. The wonderful countries you'll visit! The memories! And this is aboard one of the best ships in the world.
I love Mariner because it's spacious and so laid-back. Passengers and crew are friendly and warm to each other. Cabins are very large and comfortable and you'll have the choice of four restaurants to dine in.
No better ship for a cruise. It will quickly feel like home.
