We choose to stay at Tepuy Lodge and loved it there and were most grateful for the service from Kavac tours. Felix took great care of us, especially my husband as he wasn't feeling his best. The boat ride is a hoot...lots of fun, beauty and wonder. I had reservations before we left based on other reviews yet found everything/everybody to be great. Yes, tardiness is a local trait and our tour was delayed by a few hours (darn, would have liked more time up river). Going up rapids defies logic and made me gasp and laugh all the way. Hiking to the falls isn't too tough, just that to look around I had to stop as when hiking, I watched every step I made due to the roots. When we arrived at the look out it was worth every step, "POW, right in the kisser". Dinner was good and sleeping in the hammocks well worth the adventure (with ambien I suggest....slept like a baby). The ride down is more fun again and then we choose to take the flight over Angel Falls and it was AWESOME...don't miss it if the weather permits. I recommend Kavac and didn't see any difference in the different tours. Have fun, I know you will; it's a trip of a lifetime.
