I have done a lot of cruise diving in the past eleven years, and there are many good comments in the above posts. When deciding who to dive with at a specific port I evaluate the following criteria:
1. How long is the port time and what are the arrival and departure times? If a long port time, and the arrival/departure times are compatible with the local dive op schedules, then I have maximum flexibility to choose whether to use the ship's excursion or a non-contract dive op.
2. Is the ship docked or tendered? If a tendered port, divers that do not have any priority disembarkation (loyalty status perk) would probably be better off using the ship's dive op. The reason is that the ship's excursions are given priority for the tenders, and if the arrival time is pretty close to the non-contract dive ops departure time, you may not be able to get off the ship in time. I have been on numerous cruises where divers that had booked with other than the ship's dive op could not get off the ship in time, while I had two wonderful dives using the ship's excursion. This has been an ongoing situation at Grand Cayman, especially if the winds are up a bit, and the tender operation can be very slow if a lot of ships in port.
3. Who is the ship's dive op? In most cases, I have had no issues with the ship's dive op, and not infrequently would likely have considered/used them anyway. Just realize that your fellow cruise ship divers may not be up to your dive capabilities, so you may get a more shallow, less challenging dive that you would prefer. However, this could occur just as easily with a independent dive op. I enjoy the dives no matter the dive time or low experience level of fellow divers. It is all good.
4. Lastly, I evaluate how much it is going to cost me should I miss the ship's departure time while using a non-ship vendor? Frequently, the potential cost of trying to catch up with the cruise ship, or having a pissed off wife, if you don't make it back in time, far exceeds the few extra excursion cost or additional 10-15 minutes of dive time that you might get with a different vendor.
5. I always carry all of my dive gear, so I do not have to consider the cost of equipment rental which is usually included in the ship's excursion.
