Indiana Jones et Le Temple du Peril is one of the best rollercoasters in Disneyland Paris. We also really like the Crush Coasters and Rock 'n' Roller Coaster.
Buzz Lightyear Laser Blast (aka Astroblasters) - one of my family's favorites!
Sleeping Beauty meet and greet. At Disneyland in the US everyone lines up in an orderly fashion and waits their turn. In Paris the crowd rushes the character in an orderly fashion...
On a trip like this I like to wear Converse, jeans or shorts and a pretty T-shirt, and a cardigan topped off with a scarf to still give me a little fashion flair. We always have a stroller, so that means I will leave diapers (when we used them) and sippy cups in bottom and then a tote bag or little back pack that I take with me once we park the stroller. It usually carries lip gloss, advil, face wipes, hand-sanitizer, our camera and sunglasses. On this trip we bought a pack of Mickey-shaped lollipops that stayed in the bag as well- it's nice to have something to occupy little kids when you are in line :).
