Kim, I need to qualify first I am not on the island currently will be going Jan-Feb so take this for what it's worth. We used Elbert Greer at http//subalessonsbelize.com and arranged ahead to do the written stuff online before we left for Belize but through him and then did the pool and out to the reef on our arrival. It was that or 55 degree water off CA at catalina, it was a wise choice. It was about 4 years ago but he and his staff were great and I think he is up on the North side of the island still not as far North as you're staying though. I don't recall the cost but a guess would be 200-250 US. I think your concern will be transportation to and from town for supplies but someone else should have info on that. The scuba class will pick you up at your resort. Have fun and be prepared to come back often.
