When I booked, I was worried about being scammed because there was no license plate number or contact confirmation. Actually, it was a lot of fun; there were vehicles painted with elephants that picked us up, making them easy to recognize. But it's still more convenient to buy a local SIM card that can make calls.
The drive to the elephant camp took about an hour. There were various activities, and lunch consisted of fried rice, fruit, and spring rolls.
