Ahoy there, Kristen! Thank you for sailing by planDisney before you sail away on Disney Cruise Line.
While it is okay to bring a standard-size umbrella onboard, you will not be able to attach it to your chair on the deck. There isn't much shade on the deck near the pool, so I suggest packing a hat and sunglasses. If you are visiting
Disney Castaway Cay or
Lookout Cay, there are plenty of umbrellas on both the family and adult beaches. You will not need to provide your own. If you are going on a
Port Adventure, those are independently operated, so I can't speak to them, but there are usually chairs and umbrellas available for rent if they are not included.
If you need more suggestions on what to pack, I like to use this
packing list. If you have any other questions,
planDisney is here to help! I hope you have an amazing cruise, Kristen.
Bon Voyage!
