I booked the Dolphin Encounter direct on the Internet and saved about $50.00.
Book as early as possible. I booked two months out and could not get the time slot I wanted.
This was in May and I think there has been a price increase since then.
It was a GREAT adventure and my Devina speaks of it often. The pictures made for a great 'show & tell' in the third grade this year in school.
I highly recommend this excursion.
