Towncar transportation

Good Morning

I'm using Fl Tours for my transfers from the airport to WDW then to the port and back to the airport. I usually tip with each leg of the trip but I've never had this many transfers before. Do I pay for all the transfers at once? Also we have a limo from WDW to the Port. I know that includes a tip. Do you tip any additional amount on top of that?

Thanks so much.
