You'd think I'd know this by now, having done it several times, but I wanted to get other opinions. In trips past, I've done 10% if I know it'll be the same driver both ways. For this trip, we're having the same driver take us for four legs, from airport to resort, to Port Canaveral a few days later, then back to the resort, then back to airport, whew! So how would you do it? Thats alot of tipping! I don't want to go broke, but I want to do the right thing. Thanks.
