In my opinion a lot of the Paris versions of Disney classic rides are alot better such as Big Thunder Mountain, Pirates of the Caribbean and Rock 'N' Rollercoaster. Random tips off the top of my head are:1. Brace yourself on Space Mountain; while the effects on the ride are amazing, the ride has become very, very rough.2. I haven't been since it opened but Crush's Coaster is supposed to get pretty nasty queues and has no fastpass option due to low throughput (imagine Spinball at a Disney park) so get there at opening.3. Armagedon is a pretty poor attraction due to how long it takes to decide the show's language and it feels pretty underwhelming.4. On quite a few rides with pre-shows and dialogue onride, you can request the English version instead of French and the Cast Member may change it depending on which languages the other guests peak. I know this can be done on The Tower Of Terror.5. The front row of Big Thunder really sucks due the view being obscured by the front of the train. The back row is much, much better.6. From a site I just checked, the ERT is pretty limited: it is only on selected dates and the only rides garanteed to open which pull big lines are Dumbo, Peter Pan and Space Mountain. It does give the impression though that other rides in Discoveryland and Fantasyland open. When ERT does it happen, it is always 8am to 10am and never after park closing due to very low numbers when after closing ERT was run I think.
