The lady at Perfect Gift (no, not Shirley) recommended them to include in our gift basket. We ended up forgetting them in our room for sailaway!!
I'd try Toys R Us. They usually have bubbles all year.
I just bought some "edible bubbles" at our local science museum. They were blowing them in the store and it was a HOOT to watch my kids catching them on their tongues like snowflakes. Thought maybe I'd bring those along next time and let people think my kids are totally WEIRD!
I bought the little white ones that are used for weddings at a party store that lbgraves mentioned.
I bought a bunch and passed them out to the kids on board, they loved them.
I would highly recommend against the "sticky bubbles" otherwise known as catchable bubbles. They stick to everything, leaving a film. I had numerous bubble stains on my clothes, and peeled bubble residue off my camera, which had been around my neck during sail-off.
We bought some at drugstore near our hotel in Orlando and took them on the Wonder. We were blowing them from our verandah as we sailed away and the bubbles floated all along the side of the ship. I heard a lot of "that's a neat idea" comments as the bubbles passed by other verandahs.
