I have a question regarding the Saturday dives. We are newly certified Open Water (Got certified in Mermet Springs, IL quarry) and will be arriving to CSA on Friday 11/23. We want to be able to dive on Saturday since we will only be at CSA for 4 nights. Will we be able to sign up for the Saturday dives on Friday when we get there? This will be our 5th trip to Couples, but first time as divers. How does it work? Do you sign up day before? If we get to the resort around 3pm on Friday will that be enough time to get on the Saturday list? Just worried because we only have Sat, Sun and Mon to dive and we want to dive as much as possible.
