Mega Rafting was somewhat fun on the journey, except the tour guide kept "joking" with me every two seconds. I wanted to punch him after the tenth time in ten minutes.
I went on a private trip with the guide and my father. Again, sights were nice. Everything else sucked.
THEN, the food at the end. I don't know why I didn't think about not eating it - I was so exhausted. But I did. Disgusting, covered in flies, I think it had been sitting out for days.
Now, I have a parasite in my stomach, a temperature of 103.0 F, and I am barely able to eat or use the restroom. I went to see an Indonesian doctor who was barely any help. Now, I'm back in the US and am testing for which parasite I have.
My immune system is so low, I also now have bronchitis.
I suggest you skip Mega Rafting and pay the extra for a different company.
