Hi Ronnie,
I live about 20 miles northwest of Orlando. Just north of Ocala in Williston is Devil's Den. It is a nice cavern dive that you can dive with an OW certification and I think your wife can also snorkle there. They have air tank rentals, too. There is also Ginnie Springs which is an easy drive (a little over an hour?) from Ocala. Your wife will be able to snorkle there, too. From Orlando, you can try out Blue Springs in Deland which is a state park so it isn't that expensive. You have to have a buddy to dive in Blue Springs. I live just a few minutes away, so if you let me know when you are coming, I may be able to join you. If not, I am sure someone else here might be available. Unfortunately, Blue Springs doesn't have tank rental so you will need to find a shop in Orlando to rent some tanks if you need to. You can find all these places on the web with a search. Since these are spring dives, the water will be about 72 degrees so you and your wife will probably want a wetsuit.
Hope this helps,
Deana
