I've just found your thread! Obviously I've already replied to some of your questions on the other thread.
Where to eat depends on how long you're willing to take out of park time. If you can manage it, I would really recommend Walt's. Table service restaurants will only be open for lunch at that time of year, so you'll probably struggle to fit anywhere else in.
We were there the last week of February this year, and it coincided with school holidays in southern France. It was supposed to still be a quiet time, but the lines were the longest I've encountered at a Disney park. If that's the case for you, make sure you shortlist your 'must-dos' and focus on doing them first.
If you're a thrill-seeker, make sure you do Space Mountain. It's the best version by far in my book, definitely bigger on thrills
Other rides that are 'same but different' that you might want to try are Phantom Manor, BTM and POTC. Buzz Lightyear seemed to be very popular and was pretty much the same as other versions, so if you're short on time I would give it a miss. And their version of Indiana Jones is an actual rollercoaster. The queue was well-themed, and the ride was fun, but I wouldn't rush back there. Make sure you check out Alice's Curious Labyrinth - great fun! The parade is nothing special, don't bother to spend precious time staking out a good spot.
The Studios is kind of similar to Movieworld. There's not that much of interest there, but make sure you get over there for Crush's Coaster. Get there at opening and go straight there to avoid lengthy queues. If you're not quite quick enough, we found it was better to go and shop/have breakfast for 20 mins or so and go back. The line was actually 15-20 minutes shorter. But whatever you do, don't leave it until the afternoon. Also in the studios is RNR and TOT if you're into them (but they are the same as other versions). Do not bother with Armageddon. I still don't even really know what it was supposed to be, just a big waste of time. There are a couple of shows. Cinemagique was clever and worth seeing. Animagique was cute, but missable if you're short on time. I wouldn't even bother with the car stunt show - it's the same stuff you see everywhere. Also Toy Story Land might be worth checking out for something different if you haven't been to HKDL. The parade over there is kind of different with the characters riding in their cars, but again, not worth spending precious time waiting for. You should be able to get a decent spot without waiting anyway. Try near RNR if you're interested.
Whatever you do, make sure you see Dreams at least once. It is the best Disney show I've seen. You don't need to stake out a spot far in advance if you're happy to have a few heads in the way - the view of the show is fine from further back. We stood on the edge of the footpath to at least get a bit of height. If you can get a spot behind one of the garden beds, I highly recommend it, but they're usually the first to go and you won't have time to spend hours waiting in the cold!
As I have mentioned, be prepared for it to be cold. We spent time in Switzerland and Austria on the same trip, going up mountains. We were coldest at DLP. And you may or may not get snow. Layer up!
DLR is my very favourite park, as I think you can really feel Walt's prescence. However, DLP is very beautiful and well worth seeing. The CMs are not as 'out there' as the ones in the US, but most of them were friendly and happy to be there, and wanted to talk to us about our travels and Australia.
In Paris itself, be warned that the Eiffel Tower is closed when it snows. So if the weather is a bit dodgy over there and you really want to go up, make sure you do it when you've got a bit of a clearing. We went to the Arc de Triomphe instead, which was still open, but with a small section closed off. Paris is very easy to get around on the train, so you can save money on accommodation by not staying right in the touristy area. We did a Fat Tire bike tour which was fun, and I surprised mum with a carriage ride, which was pretty magical in the snow.
Anyway, this is turning into an essay. If you have any specific questions, yell out. Feel free to check out my TR (in my signature) to read about all the details. You can skip straight to the Paris/DLP sections.
