We chose this cruise for the itinerary - we wanted to see Vietnam and Thailand. The cruise starting in Hong Kong and ending in Singapore was a bonus. If you are looking for a cruise with lots to do onboard or for families with small children - this may not be the ship for you. It's a quiet and classy ship with outstanding service, but not a lot of the activities the mega-ships have.
As I said - we chose the cruise for cities it was going to And the ability to get closer to the main cities than larger ships was a big difference. As as example - larger ships are a few hours from Bangkok, where the Journey was maybe a half hour from the city (more with traffic)
The entertainment (and cruise director) were first rate - I did not expect a ship with just over 600 passengers to have the quality of shows that they provided.
The main dining room was better than any other main dining room we've been on (though Aqua Class on Celebrity may be a bit better), and many passengers chose to go to the dinner buffets - where a different country's food was offered each evening. The specialty restaurants were fine, with good service, but I'm not sure they are better than the main dining room.
The cabin was fine - lots of room for putting clothes away. And even though tips are included, the cabin attendants were outstanding (we gave a bit extra there)
