I generally don't recommend inexperienced divers to do that particular dive, as it's very deep and short (not far removed from a bounce) The other two dives in that day are excellent, though, and if there are enough divers (at least 10) we like to arrange a 3-dive day trip to Lighthouse reef but leaving out the BH.
Another area regarded by many as a superb divesite is The Elbow at the southern tip of Turneffe Atoll. To my mind it's not quite as good as Lighthouse at its best, but you still get three very good wall dives, varying in depth from 90' to 50'. For less experienced divers this is a better bet. It's also a fair bit cheaper, partly because operators charge less (it's closer so less fuel is used) and also because you don't have to pay the $40 tax required for the BH day.
Either way it'd be a good idea for you to do one or two days local diving before you go out to the atolls, and if you're going to do the BH I recommend you get some deep diving experience before the day. The BH dive takes you (nearly) to 150', which is beyond recreational limits and I'm sure a lot deeper than you will ever before have dived.
