As a former Dive instructor, as many other have said, do as much of it as you can at your home.

It will be a better expirence for you, you will have the option to get your own equipment (as much of as little as you want) and you will know how the equipment workd FOR YOU. Diving sucks if you have equipment that doesn't work... leaking mask? seems simple... Not at 60 foot... Yea, you will learn how to "fix" that problem, but after a couple of times, you'll wish you had good equipment.

You can do your open water check out dives in Belize with a simple referal from your local dive shop.
