For the money, this experience wasn't too bad. We did see a few dolphins while we were out, so that was cool. The guides were pretty fun, and they were also knowledgeable in regard to certain facts they shared with us along the way.
I have to go with 3 stars/average over 4 stars/very good though for a couple of reasons. The ride was relaxing but the overall experience was a bit anticlimactic. It's a fairly small area that they cover, and there's really not a whole lot to see during that hour since we only saw dolphins for maybe a total of 5 minutes. I also felt like they were struggling a bit to stretch out the experience to be an hour long. It seemed like we were going much slower going back, so I guess it would have just been nice to maybe go out further, or even stop in the areas where the dolphins were.
Again, overall, it was a nice experience, and it was very inexpensive to do.
