Great trip, long day but worth it, bus was modern (USB charging ports and WiFi, albeit limited capacity, seats reclined somewhat for sleeping) and the guide (Jorge) was excellent, very friendly, kept things moving with a nice manner and extremely knowledgeable with the ability to break up the long day in a way that it didn’t seem exhausting. Would recommend but the right guide is essential I would say, kids (11 &12) complained very little which says it all.
