Carnival airport transfers

Has anybody used carnival transfers from Hobby to the port? What time do the transfers start in the morning. Sailing on the Breeze in May. Thanks for the info.

We have done it twice, will be doing it again next month.

The first bus is around 9:30am, but you can check in 9-ish. There will be dozens of people, so check in as soon as you can. It is down by the luggage pickup, someone will have a sign and there is a desk.

It is about an hour drive from airport to port.
