If the trip goes, you should love it! It is a tough dive for your first ocean dives, so really pay attention to your air, depth, and navigation.
I would suggest you really stay close to the morring line. Don't loose sight of it. Always swim into the current. Make sure you start you ascent with at least 800 psi or more. Don't go below the allowed depth. You can do that easy on some dives, so just keep an eye on the depth gauge.
Also, when you surface using the mooring line, follow it to the side line, then catch the ladder line. After that, then put your fins on your hands, as the DM will show and pull your self to the ladder, time getting on the ladder when it is lowest in the water. If you surface using the lines under the boat, it is much more difficult, so I suggest the mooring.
Oh, and make sure that you take your seasickness pills starting 24 hours before the trip. If you can, see a doctor and get the patches, I hear they work best.
I loved the trip and had a great time by doing just what I said above. Never got yelled at, never had to be picked up by the boat of shame, and never sat out a dive.
