Louma:
Unfortunately, the Diving Site closed a few years ago. I use to dive master there. It was a fun shop to dive with. Most of the assets were bought by Tilden's. They're a good operation. There are tons of good sites from Sombrero Lighthouse to Duck Key. Most average less than 25 feet. You should have a great time there. Hope for the blue water to push in and calm winds.
On a side note, you have to go to the Key Colony Inn for lunch and have the Snapper Amandine, I swear it will be the best lunch you'll have.
It's a great place for dinner too.
