We did a 2 day VIP package in October (only 1 and 3 days on the website at the time, I wrote and asked for 2 days) as one of our honeymoon activities. Overall, this was one of the highlights of our trip and an EXCELLENT experience. It was exactly what we were looking for.
We were situated by ourselves in a cabin on a hilltop that looked to be part of a retreat area. It was air conditioned and had a hot water shower (very helpful, as we bathed 3x a day given our itinerary). There were many other cabins there, but most were empty, so we felt like we had the place to ourselves. Meals were served in an open air dining area, where we were again on our won. We enjoyed 2 full days with an elephant apiece, along with a mahout for each, a young girl who spoke very good english and explained everything to us, and a young man who followed us around with a video camera and took pictures--at the end of the trip we were surprised to get a CD with a very well made video recording of our experience, as well as plenty of pictures (a godsend given my camera batteries had died just as we arrived here!! (and there were no chargers handy)).
We spend one morning learning about commands for riding the elephants, then practicing basic maneuvers, getting on/off in a variety of ways, moving here/there etc. Plenty of different occasions riding them, either just getting from place to place in the reserve, picking them up or dropping them off in the jungle, or on a long jungle trek which we did on the 2nd day. Went to the river bed and bathed with them a couple times. Feeding them was also fun--nothing like watching an elephant tear through sugar cane like it's soft grass. One afternoon, we stopped by the circus and ran into a bunch of folks doing the regular itinerary. Our 2 elephants were older and huge relative to the younger ones in the circus. These younger ones were very well trained, but it seems that itinerary is very repetitive.
Plenty of time to also walk around and visit the elephant nursery and hospital.
We had to fly to Chiang Mai suddenly the day before, as floods had shut down train service. Very easy to arrange for a private car the night before to take us directly to the TECC camp and pick us up the following day, though a bit pricier.
