Scuba Lessons

I got certified in 98 and went on many awesome dive trips with groups of 15-20 people for the first few years I was certified. What a great experience. The Scuba Shop in Eagan has a great pool in their facility. Took a refresher course there a couple years ago with my niece. They have discover scuba classes for cheap. I Own great gear but find that when I travel anymore, I usually just rent gear except for my own mask, snorkel & fins, which can make the difference between a fun, comfortable dive and one you struggle with.
Where will you going on your cruise? Maybe I can recommend a dive outfit to use for a resort course.

Do it!

Here's a few photos I have taken while diving:
