Leaving this here for anyone searching for information (in the future) about visiting the dragons...
As others have hinted at, the tour on Rinca is now very tame and you are somewhat physically removed from the dragons (compared to previously).
Anyone who has been to the park will know they have now built an elevated walkway from the dock into the park. On the plus side this means you can (potentially) spot dragons at a greater distance, however you will not be able to get as close to them as what was possible previously (which was not "really close" however you were at least "on the ground" with them).
The other positive part of this is that the older, fatter, dragons are no longer hanging around the garbage behind several of the buildings (which mostly guaranteed sightings, but also usually meant very lethargic dragons near the ranger station, etc.)
It's worth mentioning that the best way to see the dragons now is by water (which will mean being on an LOB). Many of LOBs today still offer spending part of a surface interval (or end of day, near sunset) cruising in a tender along the shoreline... dragons are often spotted on the beach (or even in the shallow water). Shots taken from this viewing perspective are way more interesting than anything you can experience in the park. It's also interesting to consider that you can find images online of when LOBs would actually drop guests off on these beaches so you could get much closer to the dragons (sharing the beach with them). This is now illegal, but some of the images were amazing.
Last- for the person who mentioned that they had seen 'large monitor lizards" elsewhere, so they don't really understand why visiting Rinca or Komodo to see the dragons would be interesting... that's like saying you've seen reef sharks before so seeing a white shark wouldn't be interesting. While all Komodo Dragons are monitor lizards, there is only species of Komodo Dragon, and after seeing one hunt (a baby monkey, a small deer, etc.) you will never mistake these species in any way.
Consider that Komodo Dragons evolved from an ancient reptile that likely grew up to ~18 ft long, and close to ~4,000lbs. It is believed they preyed on pygmy Elephants that lived in the region. When you see a Komodo Dragon today, you are not looking at "just another lizard" - you are looking at the animal that has evolved from the apex terrestrial predator for this region.
