Disney have partnered with Orange Wifi to provide wireless internet access in all their hotels. I used the service when we stayed at the Disneyland Hotel last New Years. They offer the following options:
1 hour of Wireless Broadband Internet connectivity to be used within 30 consecutive days from first log-in - EUR 4.50
24 hours of Wireless Broadband Internet connectivity to be used within 24 hours from first log-in - EUR 9.90
3 hours of Wireless Broadband Internet connectivity to be used within 30 consecutive days from first log-in - EUR 10.00
10 hours of Wireless Broadband Internet connectivity to be used within 30 consecutive days from first log-in - EUR 15.00
50 hours of Wireless Broadband Internet connectivity to be used within 90 consecutive days from first log-in - EUR 50.00
If you use it, make sure you save the provided login details to your laptop before disconnecting otherwise you have to purchase another session to logon
I used the wifi in our room at the DLH every morning for work and it was very efficient, we never had any problems. Just make sure you have a credit card.
