We actually stopped at Lenbert's house on our crawl (he got out, we didn't) - he needed to get another battery for his camera. All I can say is that it wasn't on Pee Wee lane...
We tipped him 3,000 JA (for 2) but we had a blast and a very small group. There were only 7 of us that day, so not as lucrative for him...
Do a search here for One Love Bus and you'll find lots of info. The bar crawl is free, you just need to tip the driver (Lenbert) - hence this thread. We did 6 bars in total, he picks up around 2:30 and goes till sunset. We went in December, so sunset is early, could be dangerous later in the year?? Maybe he picks up later? You have enough time for a drink at each bar, if you don't nurse your drink.
