So...we are taking our 3 kids age 7,5 and 3 to Disney Paris for 3 days after Easter Monday. Place looks overwhelming - what should we aim for with such small kids=advice appreciated.Thanks

In 3 days you can see most (if not all) of the park so just take your time and don't rush around too much. Your kids are too small to go on the major attraction rides - the ones that have the biggest queues - so that'll be a help. There is most in Fantasy Land for their age group so perhaps spend a whole day there and then split the other three 'areas' up over the other 2 days. Main street is quite small and is just for shopping. the place is not as huge as it looks on a map, it's quite easy to get around, and manageable in the area 'chunks'.

The parades are good too, especially the evening one where everything is lit up by millions of lightbulbs!

I'd avoid trying to get autographs off the major characters - they ignore anyone without an official Disneyland autograph book (as we found after our son was snubbed repeatedly) and it is like a rugby scrum to get one. Mad mothers physically lifting other children out of the way to get their darlings to the front. Our son was 9 years old and still got picked up/shoved/jostled around so we gave up on it. Just wave from a distance and get close in for a hug from the supporting characters. The kids will be just as happy.

We have found that the best way to get autographs is to book the character breakfast package; the breakfast is actually pretty reasonable, and the characters will stop at each table for photos, autographs, etc.
My wife takes her Brownies every year, and ALWAYS books the breakfast to save disappointment for the younger/more timid kids.

3 days is a long time for Disneyland. It is larger in area than Anaheim - but w/ fewer rides. There are more sit-down restaurants but as for rides and attractions - not as many. Be sure to use Fast-Pass for all the popular rides. And the Movie Studio park really has nothing much of interest - an hour or 2 absolutely tops. Even w/ thee small kids in tow - 2 days would be more than enough.

Don't neglect Walt Disney Studios. There are lots of "shows" (versus rides) so it is possible to spend a day there without getting sore feet.

I agree with not getting character autographs. There is NO QUEUE, even though the characters have "handlers" just like they do in the US. Your kids have to FIGHT for autographs, which is not pleasant. The Queen of Hearts was so in character that she wouldn't give our kids an autograph even when they got up to her.
