If so, are there any suggestions on how much time to spend at each or any tips or suggestions to maximize time!
I didn't think much of the Studios park -- unless you're trying to check off having visited every Disney theme park on Earth, there's so much to do in Disneyland that I'd suggest just spending the day over there instead. When the Ratatouille ride opens, that might change, but for now I don't think a huge line for the Crush Coaster, a few kiddie rides and a handful of dated shows are really worth sacrificing time in the wonderful Disneyland park.
That seems to be the consensus about the studio park, and I'm leaning toward just doing Disneyland!
If you do want to visit both parks in one day, I would recommend arriving at least 45 minutes before the Studios park opens (an hour would be ideal). This is because instead of a rope drop, guests are free to join the queue for any attraction immediately after they enter the park(although they don't start loading until official opening time). Go straight to Crush's Coaster, and with luck you will be off within about 45 minutes of opening. Get a Fastpass for either Rock 'n' Roller Coaster or The Twilight Zone Tower of Terror, then ride the other. Once you've used your Fasspass, get over to Disneyland Park. Nothing else at the Studios park is worth it if you only have one day (unless you're a show person, in which case there are a few good ones...pick only one or it will be too much of a time drain).
At Disneyland Paris, make sure you take full advantage of the Fastpass system, as the lines can be insane (on my visit, almost every ride had 60-90 minute waits for a majority of the day). I would consider the following six the park's must-see attractions:
Alice's Curious Labyrinth
Big Thunder Mountain
Le Chateau de la Belle au Bois Dormant
Pirates of the Caribbean
Space Mountain: Mission 2
Other than that, the park's got a lot of similar attractions to the US parks (although mainly in French), and a number of walkthroughs that are good for killing time while waiting for a Fastpass. Other than Space Mountain and Big Thunder Mountain, the park also offers Fastpass on Indiana Jones et le Temple du Peril, Buzz Lightyear Laser Blast, Star Tours, and Peter Pan's Flight. Also note that single rider lines are practically non-existant at Disneyland Paris (there may be one or two at the Studios park, but I know for sure there are none in Disneyland Park).
One final note...if you have the flexibility to pick a date of visit during your trip and there is a weekday with a chance of rain, go then. On my visit, a rainstorm moved in around 6 P.M. and it pretty much killed the lines (Space Mountain: 80 minutes to 15 minutes, Big Thunder Mountain: 70 minutes to 10 minutes, Phantom Manor: 45 minutes to a walk-on, Star Tours: 60 minutes to 5 minutes, etc.). Even when crowded, the park is still enjoyable, but you have to be sure to plan your day carefully if you want to get everything done.
Yeah, just reviewed the Crush coaster & if it's popular as you guys say it is, I can skip that & the park. Not worth losing time to ride that.
It seems like the studio park would take up too much time while trying to squeeze everything in a single day.
With that being said, I still think two days is in order to really enjoy it all. Disneyland Paris is my favorite Magic Kingdom park because it has both rides and the scenery
