My husband and I were the only 2 on tour, max of 6 total on tour. We saw lots of dolphins within 15 min of tour starting (9am). Went out to bay first with many dolphins, then to Gulf of Mexico and saw cannonball jellyfish. Had a short stop on bay that led us to a small trail on Shell Island that took us to Gulf side of island. Picked some shells and headed back to marina and saw several more dolphins. Very good and small "boatique" service (get it, boat/pontoon). Very great service from Zach! Will do this again.
