Hope you have a great time. I would definitely recommend taking your own personal dive gear. Also be aware that all of the “rental” gear (its included) is good but the BCDs are not weight integrated. They have weight belts and weights there. I mention it because some folks have only trained with weight integrate BCDs vice weight belts.
I did not personally see a need for NITROX while there. With the two tanks a day Included dives and one more night dive if you wanted to pay extra there was just not enough bottom time for it to be needed unless you have some risk factor or just want to for other reasons.
One other note, the boats do 2 tank dives in the AM and one tank dives in the afternoon. The morning dives go out to the farther, and much better locations, whereas the PM boats stay closer to the resort and the diving is good but nowhere near as good as the AM trips. Generally the AM trips were back by lunch so you would be back in time to have lunch with your wife.
