I just did the Big Blue Explorer in Palau. A large boat, the B cabins vary in size, but the honeymoon suite has a queen size bed. The others have a double and a top bunk. Not huge rooms, but comfortable enough. 2 chairs, a desk and ours had a decent sized bath. i of the rooms was pretty small. Noise was never a problem. I never heard anyone in the other rooms. It had a large front deck with a hot tub. The food was good. A chef from the Philippines. The crew was great, very accomodating and experienced. I'd highly recommend it. It's not an Aggressor, not as high end. One person described it as "slightly run down", but I think it was quite comfortable. At almost 200', you weren't tripping over people, and could always find a quiet place to reflect. We had the option of 5 dives a day. It was the best dive vacation I've had and highly recommend it.
