I just got open-water certified last August and have my first opportunity to use it. I'm going to Puerto Vallarta for business and will have a day free while I'm there to do some diving. Does anybody know a good PADI-certified outfit that has good excursions for a day? A lot of companies pop up on Google. Thought I'd check here and see if anybody has experience with a company that offers a good diving experience. Let me know as soon as possible, as I'll be diving on April 20.
