Internet access is available onboard for $0.75 cents/minute. For unlimited access during your cruise, the price is $39.99 on the Wonder and $89.99 on the Magic. Only one member of each family needs to purchase the unlimited package. Other members of the family can share the access package, but only one person at a time may use a single access package. The Internet Cafe (at least on the Magic) is located in a corner of the Promenade Lounge on Deck 3, just forward of the Aft elevators. Teens may also access the Internet from terminals in Common Grounds. There are eight terminals in the Internet Cafe on the Magic and, at times, all eight terminals were in use.
These are just Internet terminals (although they also have AOL loaded on them). That means you can't upload photos from your digital camera and you can't run common business software. However, tezb advises that if you have a laptop, you can download your photos onto a floppy disk, and then upload from the floppy into your email at the Internet Cafe.
Before you go, make sure you can access your e-mail through a web interface. Most e-mail providers do have this option. If not, you can set up Yahoo! mail to retrieve your POP3 e-mail through their web interface.
Disney does offer an e-mail address for you to use while on the cruise if you don't have an existing e-mail address, but you pay $3.95 every time you use this cruisemail.net address in addition to the per-minute charges. Definitely use your own web-based e-mail access.
The access speeds are generally very fast... certainly faster than my dial-up at home, but things can slow down if they ever have problems connecting to their satellite.
If you have any questions while onboard, the managers of the Internet Cafe are very helpful and more than willing to help you
