Thanks ya'll. We wish we were back there too!
Tracey and Tammy - we're looking forward to seeing you again too. Sleddog - we'll see you and Azar on the Mexican Riveira.
About the underwater cameras - our primary point and shoot is an Olympus Stylus Tough 8000. It's waterproof to 30 ft, crushproof, shockproof, and freezeproof. Because Ginny and I went on separate excursions in Belize, we also picked up a relatively inexpensive Fujifilm FinePix Z33WP ($125) that I used for the Belize catamaran and used to take pictures of Ginny underwater. The snorkeling pics are coming from both cameras and I really can't tell the difference.
