The last time I sailed out of Port Everglades was about 4 years ago, so hopefully someone who's been there recently can update us if things have changed.
We dropped off our large luggage prior to parking and tipped the guys a few dollars. We then parked and walked back to the terminal with our carry-on bags. I know the terminal and parking facilities have been expanded, but when I was there it was a relatively short walk to the terminal. We arrived at 1:00 p.m. for a 5:00 p.m. departure and didn't even experience much of a line for embarkation.
When we returned after the cruise, we schlepped our own luggage to the parking lot, but there were porters available for those who needed them.
