Sorry, I wasn't trying to compare the Maldives to Bora Bora.
I was trying to say that a hotel's house reef, even when very good, is often not as good as what else is out there.
If you're that serious about snorkeling/diving, have you considered the FS Explorer? Itineraries start at 3 nights and the boat is gorgeous! I think Kage posted some sale prices, too.
