UPDATE: so I appreciate everyones input and advice and Just wanted to give a little update on what ended up happening. I just got my OW certification this past weekend at Ginnie Springs and It was a lot of fun. Turned out that me and my GF, dive buddy, were the more "competent" out of everyone. We ended up practicing outside the pool and doing a lot on our own to get ready and It really paid off, they had 4 instructors there and split our entire class up. The trip had about 30 people which was then split into four groups of 8-7. It was ok for us because the instructor that we had been training with took our group but the other groups were with instructors that didn't know the students or the other way around. I can confidently say that I feel prepared to dive on my own thanks to the advice from Scubaboard and the training I got. I just wish I could say that about the other students that went on that trip....
