Three companies are used regularly by DLP forum posters on Trip Advisor.
www.ezyshuttle.com
www.isprestige.com
www.prestige-transfer.com
Don't use any transfer company that want payment in advance. Pay at the end of each trip.
Prices vary, depending on the number of people. These are private transfers, so you do not share with others. They will be waiting for you at arrivals with your name on a board, and the vehicle is usually parked right outside.
The journey takes 30 - 50 mins depending on traffic.
If you want a vehicle with a DVD player showing Disney movies, ask for this when you book. I'm not sure that ezyshuttle have them in their vehicles though, unless they have installed them since I used them last August.
Tallulah - you should have asked questions on the TA MLV/ DLP forums. We are enthusiastic about DLP, but not blind to the faults. One of our Top Questions is about smoking in the parks.
I don't agree that DLP ride loading/ unloading is very different though. I have been to WDW five times, spending at least 2 weeks there each time. Like Paris, some rides have a quicker loading/ unloading turnover than others.
Lancelots Carousel that you mention is one of the slowest, as CMs have to check everyone is wearing the seat belt. Autopia is also a slow turnover, as it is in Florida.
Rides with fast loading / unloading like Small World, Pirates OTC, Phantom Manor, Thunder Mountain, are the same in Paris and WDW, although all these 4 rides are better in Paris as newer and improved.
Many attractions in the Studios are large capacity theatres, so worth doing those when parks are at their busiest.
DLP will never be like America, as it is run by Europeans, with a majority of European visitors.
American Disney parks are run by Americans with a majority of American visitors.
There is a huge cultural difference between the USA and Europe in general. Some Europeans never queue for anything, anywhere. Some do not have smoking bans yet, so are used to smoking where they like.
Americans have been used to smoking bans for a long time, and Southerners are usually very polite - Sir, Ma'am, Have a Nice Day, etc. We have certainly seen queue jumping there though, from non American visitors.
The Walt Disney Company only own 39.8% of Disneyland Paris. It is run by EurDisney SCA, a different company. 10% is owned by a Saudi billionaire named Prince Alwaleed, and 50.2% by EuroDisney SCA shareholders.
It is generally agreed that Paris has the prettiest castle and ' Magic Kingdom' park. The Studios is only 10 years old, and still being expanded.
Some true Disney fans don't like WDW as they say it is too big and impersonal. It certainly is a huge money making machine. They prefer the original park in California, which is smaller than Paris.
I do find that CMs in Paris smile and say hello ( bonjour ) but maybe that is because I do the same.
