I've done a lot of rafting over the past 30 years on a couple different rivers in Maine and I have to say I did not enjoy this experience for several reasons:
1) It was repetitive. You go around and around the same course multiple times. It probably takes no more than 5 minutes each time, and then you circle around the lagoon and go around again. It's like riding the same ride at an amusement park over and over again.
2) Our guide decided it would be fun to flip our raft over on purpose. It was not fun. To clarify, we were a group of middle aged not terribly fit women. Why he thought we would want to be pushed to that level of adventure is beyond me. Several of us came up under the raft which was terrifying for my friends who had never been rafting before. We all ended up on scattered along different parts of the shoreline. One of my friends was so scared she refused to get back in the raft, and another friend suffered a bruised and bloodied leg so she did not get back in the raft either. Maybe the guide was trying to compensate for the monotony of going around and around on the repetitive course, but it was not at all appreciated.
3) In a word - fat-shaming!! To start out the trip they grouped everyone around for the safety lecture and then proceed to hand out life jackets... by weight. A few of us in my group are rather big-boned... okay we're pretty darn overweight. We were absolutely mortified when they yelled out that anyone over 200 pounds should come forward to get their life jacket. It was absolutely humiliating to have to wade through the crowd of people to get our hefty sized jackets in front of everyone. I think we were the only women who had to step forward for this embarrassment. I get that weight is a factor in buoyancy but surely there is less humiliating way to go about this. Again, I have been rafting in Maine for 30 years and I have never seen anything like this. Even if the rafting was worth going doing again (which it isn't), my friends and I would never go back for this reason.
