Although Tour B also offers some snorkeling, this tour is more aimed at sightseeing.
The tour starts with a visit to Lagen and Pinabuyutan Islands. In Lagen Island you find another of the very exclusive El Nido's resorts, the Lagen Island Resort. If you are looking for a romantic hideaway in a paradisiacal island, this may be the place for you (check the prices first, though!)
