This was a very nice easy paddle through mangrove tunnels, which was pretty cool in the dark with the lighted boats. We had a couple of rowdy kids that didn't know how to paddle and didn't listen to instructions, so that put a damper on our fun. But the guide handled it well, and we really had an enjoyable time.
At one point we were supposed to disconnect our paddles and only use one paddle through the mangroves. If you are experienced, I would suggest you don't disconnect, as using one paddles causes more water to get in the boat, and we got more wet that way than using just one paddle.
The kayaks are wider than standard kayaks, and don't have rudders, so even for experienced kayakers they were a little harder to steer. Going slowly will help with that (there's no rush anyway).
Much nicer way to experience an evening in Key West that doesn't involve noisy bars and revelers.
