We are currently in Bali and tried to find out who ran these VW convertible tours after seeing them in Ubud. I strongly recommend you do one of these tours as it was one of the best days we had in Bali. (still had a few days left!) The driver we had was lovely and we saw a lot of the beautiful rice fields and coffee plantations in the centre of Bali, we chose to end up with Tanah Lot and Echo beach at Canggu. However, you rent the car for the day and choose wherever you would like to go - it's totally your call. Don't miss this one - it's amazing fun! contact me on my email if you want the details.
