We're parking with them in Ft. Lauderdale, they offer free shuttle service to the piers. I'm going to drop my husband and luggage off first, then going to park and take the shuttle. We figured our drive was going to be about 16 hours, so I plan on staying some place in between. If we had to drive straight through, I know I'd be making stops every 1-2 hours for my husband to go potty. Then I'd take his water away after the first 3 times. Then I'd have to wake him up every time he started snoring. Then for fun, I'd tell him there was a naked lady on the side of the road and watch him smack his face into the window trying to find her
. Just keep telling yourself along the way, our ship awaits. Have a wonderful cruise.
