Hi Dana! Thank you SOOOO much for your help. Your explanation of the drinks/soda card was very helpful. Iced Tea sounds good to me, and I don't drink a lot of soda, so it likely isn't worth it, unless I could buy the soda card and get unlimited sodas for the 4 of us, which it doesn't sound like it.
I'm very excited about the Scuba diving cert. I just recieved my DVD and booklets today! My hubby and I are doing it together.
