David, yes, in the Rapa Nui area (and really everywhere we went), we were transported via larger vans with guides. And, tour members were able to see/do pretty much whatever they wanted, including visiting the volcano crater. What was totally cool for us is that the pilot(s) of our plane circled the island on approach twice, so both sides of the plane could get a great view/photos of the island. The one time I was without a guide was when I was dropped off for a quick stop in "downtown" to pop into a shop or two. The shop staff was not gushy...a tiny bit of language issues... but they were business-like polite. Magically, the vehicle that dropped me off appeared when I left the shop. And, "downtown" seemed to have more free-roaming horses than people on the streets. You will see horses a lot. One of our guides said if someone is looking for their horse, they just ask around, and someone will know where to find it. Ditto for dogs. One saw me as an "easy mark" and sat at my feet outside for breakfast (yep, he got a bit of bacon), and moved on to his "next mark" when we left.
Unique place. For the most part, two full days is plenty to see/do/enjoy.............and if flying regular commercial (we were not), it is a LONG trip to/fro (typically Santiago). We were able to go "a bit" more direct from Cusco to Pisco to Mataveri Airport on Easter Island instead of having to bounce down to Santiago first.
PBS has a program about Easter Island coming up this week (not sure if it has been aired before), and we plan to watch it :)
If I were pushed to describe the "vibe," maybe a bit like Hawaii, but less choreographed, and more casual/relaxed......without the crowds, not nearly as developed with hotels and shopping, and without the young international couples with photographers snapping their photos constantly. You will not see traffic jams and will not feel overwhelmed by crowds of people. Very environmentally aware. It is technically against the law to use plastic bags there.
