Ahoy there, Laurie! Welcome aboard planDisney!
Ah, towels. Whoever invented them sure could have made them take up less space in luggage, that's for sure!
I have great news, though! If you've booked
Port Adventures through Disney Cruise Line involving water or water-side activities, the crew will have towels available to pick up at whichever meeting spot onboard when you check in - including when calling on Grand Cayman! The only thing I'd be sure to pack in this case is plenty of sunscreen and a bag large enough to hold all the towels you'll be taking.
Now if you're hoping to snag a towel at a port where you haven't booked a Port Adventure, in that case, you'd be out of luck, and would likely need to plan on packing a few towels you've brought from home. Hopefully, you'll have planned an exciting Port Adventure, though, and won't have to worry!
When it comes to laundry, I can confidently tell you that there are
several laundry facilities aboard for Guests to use! With the exception of the
Disney Wish - which has a single laundry facility called Fairy Tale Laundry - self-service laundry rooms are located around each ship aboard the
Disney Magic,
Disney Wonder,
Disney Fantasy, and
Disney Dream! The best part? No need to bring detergent or dryer sheets - your Key to the World card can be used to purchase these while onboard! One less thing to pack is always a "planDrew-approved" approach.
I hope that helps you and your crew stay high and dry...well at least until you get in the water, that is...you know what I mean...haha!
Thank you so much for your question, Laurie, and if you have any others, you can always sail our way at planDisney - we'll be looking for your colors on the horizon!
Fair winds and following seas!
Andrew
