If you're taking a cruise to Princess Cays or Half Moon Cay, this little trick can earn you priority

Here's my favorite Carnival private island hack, and it involves this.

And this is the magic ticket to get yourself priority tendering, which is important because two of Carnival's private islands, Princess Key and Half Moon Key, are tenders, meaning you take a lot of time getting to and from the destination from the cruise ship.

So, having priority means you can get out there early and beat the crowds and maximize your time at the beach.

So, what you need to do is just rent an umbrella for $24.99.
