Hey there, hi there, Maureen! Thank you for sailing on over with your question.
It sounds like you're going to have a vacation that includes the best of both worlds - a
Walt Disney World vacation followed by a
Disney Cruise Line voyage. That sounds like the perfect vacation to me.
Maureen, I've read and re-read the
prohibited items list just to be certain, but I don't see any reason why you can't bring your popcorn bucket or slipper onboard
the ship with you. There will be plenty of room to store them in your stateroom, so they won't be in the way, and there isn't anything about either item that would cause them to be a hazard.
In case you're concerned about taking the items with you, you can ship them home. You can visit a gift shop at your
Disney Resorts Collection hotel, and they'll help you ship the items home. You can also visit a resort with a
Business Center, where they'll help get you packed up and shipped out.
I hope your upcoming vacation is practically perfect in every way.
Anna
