We're heading to Maui (Kaanapali) soon for a family trip and we'd like to get our 13 year old son certified. We're planning on getting the online material from PADI so he can have that part out out of the way before we get there. Who should we use? Scorpion Scuba provides daily equipment use in the pool where we're staying and would use the pool and the shore at our resort so that seems like the most convenient option. Any opinions? Thanks....
