We are a family of four, 2 adults and one 13 yr old recently certified, and one 16 year old that is not. We will be staying in Palm Cove the last of December and have two days available to dive. I have heard great remarks about all 3 and know the passenger capacities vary from 12 to 60 ppl. Of most importance to us is the reef(s) we visit and what we will see. Secondly, being that we are newly certified and/or needing an intro dive, the attention we will receive. I orginially booked us on a Tusa Dive (going to outer reefs Flynn, Milln, and/or Thetford - 28 ppl max) with a guide and another with Synergy (going to inner reefs Tongue, Rudder, or Chinamen - 12 ppl max). However, so much talk has been made of Agincourt Reef and Poseidon (60 ppl max) that perhaps I should choose them and then Tusa or Synergy? Since I can only choose two, any suggestions? Also, a 2 day liveaboard to the Ribbon Reefs would be great but a no with Dad! That is why we are choosing day trips.
