I haven't been to Japan Disneyland in over 10 years, but, it seems unlikely there would be anything Vocaloid there, officially. It would seem strange for Disney to promote characters outside of its ownership. Besides, Vocaloid characters are still copyrighted by the companies that created them. For Disney to sell any goods or promote a Vocaloid character, a contract or agreement would have to be made allowing Disney to do so. It's not impossible that a deal could be made for a cross promotion of some sort, but so far, i have not seen or read anything.
From the internet (I don't suggest this) or buy it in Japan
The Disneyland in Japan is located in the northern part of Tokyo Bay.
Vocaloid is not an anime because, well, vocaloid is a program made in Japan where you buy the characters and the sets and you can make your own videos. Sometimes they're fan-made and other times they're made by the actual people. So, to answer your question, Vocaloid is a program, not an anime or manga. Vocaloid isn't an anime, but they have made a manga of it. It's called Hatsune Mix, and you can read it on onemanga.com.
In Japan. It cost a lot of yen, though. Or you can get it on ebay, amazon or somewhere.

Yes, Ai is a vocaloid. A vocaloid 3 to be exact.
a lot of stuff -ilovehorseyrides
I highly doubt it, since Japan made that game. Most people who cosplay and have an Anime party are at Japan. Kingdom Hearts isn't in Disneyland.
Vocaloid fans like Vocaloid. Vocaloid fans are located around the world. Vocaloid fans also have a tendency to like Japanese animation (anime) and comics (manga).
Piko is the name of both the Vocaloid and the voice provider, who is naturally not a Vocaloid.
No, Hatsune Miku is not an anime. Hatsune Miku is a vocaliod. A vocaliod is a computer generated singer, but Hatsune Miku is by FAR the most popular in Japan.
No Teto is not a Vocaloid. I have heard before that She was made to be a prank. She is mistaken to be a Vocaloid. She sounds like a Vocaloid(y) software.
