not when we parked January 2020. You pay when you enter.
we have done b2b several times and you always pay for the first cruise and as long as you dont move your car you dont pay for the second leg. Our very first b2b cruise, we actually asked the attendant he said you pay whatever the machine requires when you enter. My first b2b was a 3 night/7 night on the Magic. We only paid for the 3 night. We’ve done b2b cruises at least 3 more times after the first one. Always the same.
