I would just hit the ATM at the airport to avoid stopping in town to get some cash to pay the driver.
This was great advice. Visa On Arrival cost $35 USD, with an addition $1 because I did not have a passport photo. That didn't mean they took a photo, only that they took an addituion $1. The lady in front of me was German; for her Visa On Arrival cost $30 USD. Every country can be different. Took about 5-10 minutes to clear immigration, less than I spend at BKK. I changed $20 USD at the airport (=160600 kip) to pay the taxi fare into town which was 50000 kip as I recall.
Edited to add: Visa is for 30 days, single entry into Lao P.D.R.
