I've been on a Singapore-Malaysia cruise, 70,000 tons, and should have a similar experience.
Feeling good, the ship good multi-storey, facilities are very luxurious, there are a variety of entertainment programs: swimming pools, casinos, bars, health, fitness, ping pong, bowling, billiards, theater, stage, all kinds of food and beverage, golf, playgrounds, the main cabin has a large ballroom and performance stage, foreigners are performing very lively.
The line of the cruise ship is incomparable to the land route, more famous islands, close feeding seabirds and so on. Because they are sailing near the sea, very smooth security can be guaranteed, it is worthwhile to experience in a limited life many times.
