Can you make it back your ship by lunch time (between 11 am - 12 noon) if you book an early morning dolphin encounter on either the Blue Lagoon or the Atlantis? I heard the actual shore excursions only lasts under an hour and about half an hour away from the Nassau port - so if you just strictly do the dolphin encounter, can you make it back to your ship after 2 hours of disembarking to enjoy the ship? Thanks!!
