When we cruised in November we used yourride. We had 4 adults and 3 kids and each leg of the trip Rabbit suggested we tip around 10 dollars. I had to ask him since we used our AMEX to pay for the transportation (might as well get Delta Miles for the trip right?) and since we didnt pay each leg he suggested (after I prodded and plead with him) the 10 dollars. We tipped more than that..usually 15 because the service was so good but I would think that 7-10 per leg would be sufficient!!! We had 7 stops total...MCO to Poly, AKL to Poly on morning of cruise after we spent the morning at AK, Poly to Port, Port to Days Inn for inlaws room, days inn to POR, Seperate car from POR to Days inn again for the inlaws, and then POR to MCO for the 5 of us.
Have a great time!
