Once we decided to visit Easter Island, we bought the movie Rapa Nui (Kristen had seen it before). The movie gave us a glimpse of the moai (statues) and ahu (platforms) and depicted one theory behind why and how they were made. It covers as its main story line the 'Bird Man' contest which is very interesting -- let us know if you want to borrow the movie. In theAbout Rapa Nui section we provide some of the many things we learned about Rapa Nui from our guide, much of it is either not covered or is changed in the movie.
As far as our trip goes, we arrived mid-day on Tuesday, and our guide, Alexandra, was also our transfer from the airport to the hotel. We had on our itinerary a full day tour for Wednesday and a half-day tour on Thursday. Clearly, things are quite laid back on the island because she was open to do the half-day on Tuesday and the full day on either Wednesday or Thursday. She basically drove us around in her jeep and told about the history of the island.
For lunches and most dinners we ate at the hotel, mostly because it was included in our package and there were not that many other obviously better choices. The hotel food consisted mostly of a buffet of 1 (sometimes 2) choices, always including tuna of some sort. We found out from another guest that they were charging $34/pp for the buffet if it was not included in your package -- it was worth at most $10.
