We're a couple mid 50s just back from Malaysian Cruise - Singapore, Myanmar, Thailand, Sumatra & Kuala Lumpur. Absolutely wonderful. This is our 2nd Quest cruise and from the time we boarded their shuttle to the port in Singapore, boarded, checked into room to the time we (sadly) left, we were absolutely satisfied.
The crew is wonderful and everyone from the Captain on down, made us feel like we were part of a big, happy family. It's not a large boat with a total guest capacity in the 600 range and that might help in thie ambiance. The Cabaret lounge always had nice entertainment in a warm, comfortable environment. Lots of seating, never crowded.
We typically closed each night with dancing at the Looking Glass to a DJ (thanks Alex) who served up great music and handled most requests.
Stateroom was exceptional. Good water pressure and temperature in the shower (important for most), comfortable bed, lots of storage, clean, nice balcony and room service was always efficient and timely. No complaints.
