I agree with the previous poster...never sure we'll have the same driver so we split it up...we tip between $15 and $20...depends on if we get a bunch of groceries on the way to the resort...if the driver is nice...you know the things that make ya tip better or worse depending upon the service quality. We left SSR on Christmas night, so the driver picked us up around 6...he was actually about 20 mins. early, which we liked...no rush then...he was very nice and friendly...we tipped hi above the usual...it was the holiday after all.
