Depends quite a bit on how deep you plan to go (within the limits of your certification, of course) and who you are diving with. Although I was on Lighthouse Reef MANY times in the past (working as a marine biologist on an eco-cruise ship), we could never spare a Zodiac to take divers to the Blue Hole since they were needed for our other passengers. Finally did a blue hole in the Bahamas last month and although it was interesting, there was not much life down to my max depth (112 fsw I think) and I ascended to spend most of my dive near the top where the filming was more interesting.
Another factor I always recommend divers consider when doing a dive that differs from their normal experience (such as this or solo diving)... have you experienced any unexpected emergencies so far; and if so, how did you respond to them. If you panicked, I'd recommend more experience. If not, maybe you'll be fine.
If you notch a few more dives and are diving with buddies you feel are safe and capable of handling any emergency that might arise, I'd consider it... at least to the limit of your certification.
