This was just a 3 day 2 night dive trip aboard the South Siam 3. It is a big boat, with typically more than 50 divers aboard. In spite of that our group of 10 had a great visit and never felt overly crowded. No Whale Sharks or Manta Rays seen on this trip, but it was early season anyway. For most of the group, the diving part of the trip followed 2 days in Bangkok and preceded a couple nights in Patong Beach, then 3 nights in Hong Kong. A fast paced trip for the guys, but with limited vacation time they packed as much into the time as possible.
