We spent the afternoon on the Sea Dragon and it was wonderful. Our three kids (6, 2.5, and 9 months) loved every bit of the experience. Our baby spent the whole time watching all the activity and our two oldest children felt so special because the pirate staff (Stache, Jackknife, Lighthouse) were constantly interacting with them. We saw tons of dolphins (probably 10-15) and they swam within just a few feet of the boat.
The length of the cruise was only two hours, but it was timed perfectly. Our children had a blast and never felt board. They also never really looked out at the beautiful water because they were so busy with the pirate activities (water gun fights, swabbing the deck, chicken dance, limbo, hunting for treasure, face painting, temporary pirate tattoos, tambourines, etc.).
I saw everlasting people that brought their own drinks aboard and there was not a bag check, but the bar/snack area was very reasonable in prices. Beer was 3.50, wine 3, margaritas and rum punch all either 3 or 4 bucks. Soft drinks just 1 dollar. Candy from a quarter.
Captain Phil was amazing. He kept fun music going throughout the cruise and provided hilarious and family friendly pirate commentary for the entire two hours. Kids and parents alike enjoyed his hosting.
The kids received cheep, paper pirate hats, face painting, some candy, a pirate wristband, some small "treasure" trinkets, and a skull and crossbones necklace. The adults received a load of fun. It appeared that 90% of the kids were ages 2-8.
I recommend getting there early. We boarded just 10 minutes prior to leaving the dock and we found it very difficult to find a seat. The pirate crew was very helpful, though.
Also, there are no strollers allowed on the boat.
There is ample shaded spots to be. The snack area has plenty of tables and windows below deck. The poop deck (next to the wheelhouse and Captain Phil) has lots of seating and the best views on the whole boat. There is also a windowless below deck area called "the dungeon". Face painting occurs in this space and later in the cruise Stache tells the little pirates all about how to search for treasure. The kids send 80%+ of their time on the main deck of the ship and the parents will prefer seats around the main deck. Those seats are in heavy sun, but it is worth it.
There are several occasions where the kids are split into groups of boys and girls, but otherwise everyone is always together.
All of the staff was very safety conscience, although lots of the activities involved letting the kids just play naturally. The staff were constantly looking for kids to get involved with the games and were very vigilant about gently correcting the kids when they weren't following the rules.
I highly recommend the trip for a family with kids ages 2-8. The kids are sure to have a blast!
