Sure - it was wonderful. One of favorite things during our trip last month. We booked the trip through the Disney resort, just call down to recreation or stop by their window. There are 4 of us - 2 adults, DS - 6 yrs and DD who was 2 then. The cost is "$30 per person. Children two and under are free with a 3 person paid minimum." So it was $90 for our family plus I tipped $15 as we really enjoyed the trip. Our captain's name was Mike, very pleasant and professional guy. Good with my young kids, patient with them, easy going. He scooped up a blue crab we saw swimming by and put it out on front of the boat for the kids to see (later to be returned to the water). Trip was 1 hr and 45 minutes long and the boat is small, a 6 guest maximum so it made it very personal. Our group was the only one on our tour. We saw some much larger boats out doing the tour and thought our cruise was so much better. We saw several dolphins, Mike is really good at spotting them and then cruising you in closer. We had a few come up right next to the boat. Got some good pictures, I"ll have to get them added when I can get time. Also boat has a nice canopy so you don't have to sit in the sun if you don't want to. I highly recommend this activity!
ONE BIG TIP - SIGN UP FOR THE THINGS YOU REALLY WANT TO DO EARLY!!! We didn't plan ahead and DS wasn't able to do some crafts - already full, and we missed out on Kids Night Out - what a bummer. Learned my lesson. Some things have a fee and some don't, some have a 24 hr cancellation policy (like the dolphin cruise and kayaking) so pay attention to that.
Have a great time! HH is awesome!
