When we did our FW stay/cruise/stay, I drove from FW since I prefer to be in the driver's seat and not wanting to wait for the other bus passengers.
We also did something different because we had our 6yo and 4yo DGSs with us and they had no clue about the cruise.
We drove to the port, checked into a beach front hotel and then watched the Magic pull out on Saturday. Sunday morning we drove back to the port and while DW checked in for the cruise I kept the 2 boys busy. When we could board we walked around the ship, ate some lunch, then went to our cabin and checked it out. When the older GS heard about casting off he commented that we should get off the boat or we would get in trouble. This is when I got the video out and DW says, "How would you boys feel if we stay on the ship and go for a cruise?" The responses were priceless.
Enjoy your FW stay and the cruise.
