We did last October. Our driver said he didn't have "grocery stop" on his paperwork. He did agree to stop and drove us to a Walgreen's (I think) drug store. A drug store? For wine and beer?
Then when we got to the terminal the driver said he didn't have his credit card machine and would need cash. $250 CASH (for the return trip as well).
I won't be using tiffany this October. I want to go back to Tom's Towncar, but I heard Disney has a problem with them, so I don't know what to do now.
