In July 2009 4 friends and I traveled to Medan, Sumatra to explore the island. Before arriving in Medan I got the contact information for a guy called Bob Sumatra who has a great van (seats 6—7 people very comfortably!) and arranged for him to pick us up when we landed in Medan. I transfered a deposit to him, and sure enough when we landed in Sumatra he was at the airport waiting for us. Bob helped find us a hotel that fit our budget and we set off for the Orangutan reserve a couple days later. Bob proved to be a great driver along with guide, knowing people all over the island, making our trip even more fun.
One should be careful when hiring someone online and giving a deposit, but you will not have a problem if you use Bob Sumatra in Medan,
We used his services for 18 days, driving from Medan to Padang, and the whole trip was great. Bob is fair with prices and is an honest guy who knows his way around and is a very helpful guy to know for anyone traveling on Sumatra. His contact info is [—] http://www.sumatra-adventure.weebly.com.
If you have any questions for me, my contact is firstname.lastname@example.org.
All in all, if you are going to Medan or Sumatra, Bob is the guy you want to know!
