Ahoy David –
Thanks for coming to visit with us here at the Disney Parks Moms Panel! We are delighted to hear about your Alaska cruise with
Disney Cruise Line. I had to admit, I learned something new from your question because I had no idea what a Hydro Flask was! After looking online, I found out that it is a stainless steel thermos type drinking cup. After checking on the
Prohibited Items, I did not find it there, so the answer is yes, your Hydro Flask is allowed on your cruise. Actually, I thought it was a great idea to keep your drinks cool, so kudos to you David! Make sure that you visit the
Beverage Station regularly to fill up your flask with complimentary drinks including soda, coffee, tea, and hot chocolate. Thanks again for asking such a great question and please feel free to come back because Nancy and I are so happy to help.
