Steve sends a lot of his pick ups to other drivers he works with. Since you had a party of 11, I would think it would take up a whole van. Whenever I have used SAS I have stayed at one of the hotes listed and van picks us up along with other hotel and airport stops. If you have 11, I would think your van will go direct from hotel to port.
i think the price per person is fair. I am what you call an “over tipper”, so yes I would still tip.
Whenever we fly into Ft Lauderdale and cruise out of Miami I always use SAS. So I trust Steve.
