Going to Belize in january!! Any suggestions on must sees?

[Coralgurl]

I've never been to a tropical place ever so I'm pretty excited to be doing this trip. Tickets were booked today...woohoo!

So what do I need to know, do we need shots? Part of this trip is to look at land for possible investment opportunities, the rest is being tourists! Jason likes to hike more than chillin on a beach, I'm not in beach shape myself so this would be ok! But we do want to maybe try snorkeling, probably not enough time to do scuba training.

Looking for anything you guys can throw at me, what should not be missed?? Food, entertainment etc.

Thanks!
