We used to use Disney Express, but last time as our arrival was later than the last express bus, still early though in my opinion we had booked a taxi and was surprised at how inexpensive it was. It was only 5euro more than the disney express, and that was only with 2 of us travelling, and much more comfortable, without having to wait at the airport or for it to stop at loads of hotels before ours.
From now on we will be booking a taxi. It took about 40 mins. The TGV is great but with us coming in on easyjet, I never trust it being on time to make the train, and we did go for just getting a walk on once but the next train we could get a ticket on was in 2hrs time so won't be doing that again.
