Hello, Kali! Thanks for visiting us at planDisney with your question. It's just about time for your cruise to set sail on a magical vacation!
I'd be happy to help you prepare, and I'm guessing that with your departure date so soon, you are packing your suitcases. While safety razors for grooming purposes are generally allowed on a Disney Cruise, it's the "disposable box blades" part of your question that has me concerned that they could be confiscated. Ultimately, it will be up to the security screening team to decide if your razor is safe. If you have a backup option for your personal grooming needs, I suggest you bring it.
Disney Cruise Line has a
packing checklist for your reference as you zip up those suitcases for adventure. I suggest that you pack light and leave some space for souvenirs. One of my favorite items to purchase as a souvenir is a Disney Cruise Line-branded towel, especially from one of Disney's island destinations. Not only is it practical, but it brings back some very happy memories when I use it.
One last thought before you go: make sure to have the most recent version of the
Disney Cruise Line Navigator app downloaded to your smartphone. The app will guide you to all of the food, fun, and entertainment onboard. Have the best time!
Bon Voyage,
Adrianna
