Sea Trek was beyond phenomenal. It seems complicated, but it's as easy as walking and breathing. The guides did a fantastic job at informing us about the equipment and how to use it. They calmed any nerves we had. My husband is over 250 lbs like many other men 6 foot or taller men, so there are many excursions that we can't do because of the weight restrictions. But ANYONE can do Sea Trek. A little kid in our group looked terrified going into the water, but coming out was smiling ear to ear. Since you are reading reviews about this excursion, you are obviously interested. Just do it! You will not regret it!
