Recovery is going to be your BIGGEST concern - not just during DLH weekend, but especially after. You're not giving microtears, etc., a whole lot of time to heal and then you're going to be stressing your body with a long-haul flight.
Lots of stretching, foam-rolling, ice baths, etc. I would probably sleep in compression every night from the time I get home from
Disneyland to when I leave for Paris (and definitely on that flight), just to keep everything tight and right. Also, I wouldn't force anything at DLH. There's no reason to risk getting hurt when you know you can finish and are just looking to come out and have fun. Treat the DLH races like fully supported training runs for DLP Half.
Also, don't take much time off - even if it's just cutting runs back to 30-45 minutes/3 miles during the week or so. I would try to squeeze in one more longish run between getting home from Disneyland and leaving for Paris (maybe 8-10 max), just to keep your fitness level up.
