Hmmmm it all depends when exactly you go. If during the week you can do the main highlights a day each park, but I do think 3 - 4 days is more appropriate for a visit. But let's face it, a little time is better than no time.
If on a real budget, the eTAP in Serris with the use of a chargeable bus or train is the absolute cheapest. Or you could look at sharing an apartment with the Aparthotel.
If a free shuttle is needed, then the Kyriad may be a good option. And if you want to stay on site (including extra magic hours which can be very much worth it if going for one day - easy to do 10 attractions in those 1st 2 hours), then the Santa Fe is the way to go.
For queues, the worst are Crush Coaster in the Studios (can have 60-90 min waits before the park even opens).
In DLP Big Thunder and Peter Pan get the worst waits, with Space Mountain sometimes coming in 3rd.
Do these early or last thing (warning Crush and RNR Coaster often break down).
As per all Disney Parks, Pirates of the Caribbean, Phantom Manor and It's a Small World are fast loaders.
Also, if you go to the Studios, do not miss Cinemagique and Moteurs Action - they are awesome and must not be missed.
I'm a big fan of the Disneyland Resort in California, and I've convinced my family to spend a day or two at the resort in Paris during a trip to France later this year. Does anyone know what crowds are like in September? We'll plan to visit mid-week. Any input would be greatly appreciated. Thanks!
