Bottom line: families and first-timers should prioritize Disneyland Park; thrill-seekers should pick Walt Disney Studios; if you have time, a 2-Parks day ticket is the best value. 1) Disneyland Park is the classic fairytale park (castle, parades, family rides) - ideal with kids or on a first visit. 2) Walt Disney Studios focuses on movie effects and bigger thrill rides (Avengers, Tower of Terror), favored by teens and adults. 3) Tickets come in 1-day single-park, 1-day 2-Parks and multi-day options; for a single day, the 2-Parks ticket is not much pricier and lets you hop between both. 4) The resort is in Marne-la-Vallee on the eastern edge of Paris, about 40 minutes on RER line A. 5) Go midweek/off-season for smaller crowds and frequent online discounts - book ahead and compare prices.
