Hello there, Margaret!
Welcome back to planDisney, thanks for your question!
Shopping on a cruise is always fun!I think you're referring to the insulated cooler bag that guests can buy on Disney Cruise Line ships, right? The bag can be purchased with a variety of drinks inside, which is largely what determines the price. It may be possible to purchase the bag alone, although I think getting the water in it is a better deal! Pricing is subject to change, but I would plan around $20-$30 for the bag alone. You can usually find these for sale on the
pool deck at one of the bars, near debarkation points on port days, and just off the ship if you're visiting
Disney Castaway Cay.
Because you will probably see plenty of similar Disney Cruise Line bags I would recommend bringing a luggage tag or colorful tie to add to yours so you can identify it quickly. Something bright and distinctive works great, even if it's just a ribbon!
If you want to do a little more shopping before your voyage you should check out
Onboard Gifts! Depending on your departure port, you can find a variety of fun items to start your cruise off on a high note. My favorites are the room decor packages, they're so cute and I love having a blanket onboard to take with me to watch movies.
I hope you'll fill your new bag with everything you need to have a perfect adventure, Margaret!
Keep moving forward!
Amanda
