It's what I do. Last time I flew in for a cruise the night before grabbed the hotel shuttle to the hotel. I just told Carnival I was flying the the day of the cruise and gave them an airline and flight number that was arriving around 11am. Took the hotel shuttle back to the airport around 10:!5 or so, grabbed a coffee and headed down to the baggage claim area and there they were. A nice lady with a sign and clipboard had my name on her list and was good to go.
