While the other two pieces of the trip were interesting, I don't think they're worth the money to spend on all three activities.
The animal rescue was great, but the groups were too big and I had to fight for breathing room with rude europeans.
The chocolate lady, while some pieces were interesting, I would not recommend someone spending the money. I learned more about costa rican women having babies in the woods than I did about chocolate.
The waterfall was pretty much a joke. It was a small waterfall with a bunch of locals giving you dirty looks. I couldn't get a decent picture because all the local kids were jumping off the falls into the water. The last two activities wasted half a day in costa rica that I could have used enjoying something else.
