Yes Disney can arrange a transfer to La Vallee (the outlet bit)
We've used it twice now, once from the
Disneyland Hotel in Mar 2006 and then again from the HNY in March this year.
Just go to the concierge desk in the hotel reception and let them know you'd like to go to La Vallee. They'll get on the phone to the people who do the transfers and tell you how long it should be until the driver can get there. The shuttle will pick you up from the hotel's reception.
You pay the driver directly, I think it was 5 Euro per adult return, and then he'll give you a ticket for your return.
When you want to go back to the hotel there is a small porta cabin where the driver drops you off, the staff in there will call the driver for your return.
Just one point, the first time we went it was a minibus, this year it was a Taxi as he was filling in for an ill driver. Make sure the Concierge knows how many of you there is...Fitting all 9 of you into a Taxi could be fun
Have fun at DLP
