I have gone on dives without having my own buddy along. I have been paired up with no big issue. However, I HIGHLY recommend that you talk with the person you are paired up with about signals, gear placements (where is the octo), OOA issues, and practice before you get into the water. You should be comfortable with your own gear and your ability to take care of yourself in the water. Sometimes the INSTABUDDY might not be the best buddy. Understand each other's gear and comfort level so that if there is a situation, it is a recoverable problem. If you have reservations, talk to the dive operator when you book. If you just don't feel comfortable with whom you are paired, don't hesitate to let the DM know so that you have a good experience. Never think that you are being rude if you protest who you are paired up with. In the end, it is your dive, and most importantly, it is your life!
Happy diving and dive safe!
