we're taking a Tiffany van from MCO to our resort then back to MCO. 20% min. gratuity is required & i thought that the employee who booked our reservation said to pay the 1st driver half of the 20% then the other half to the 2nd driver (although sometimes, it's the same driver round trip). did i hear correctly - is it 10% each way or 20% each way? probably a stupid question but i'm on a budget.
