Update:
My wife and I finally visited DL and DCA on Wednesday, October 14th. We had a blast !
Took HydroGuy's plan and tried it. It looked good until the very first ride.
We got FP for Space Mountain and headed for Alice but because of the rain, Alice wasn't operating. Skipped to Matterhorn, understaffed, bobsleds were wet, waited for 15 minutes to get on, but then, waited 5 minutes for Toad, Pinocchio and Buzz.
Got to Indiana Jones at 10 to get a FP....FP were not avalaible but the ride was opening so waited only 5 minutes to ride it (well, the 5 minute walk to get thru the queue, that is such a long queue). then POTC (no wait, alone in the boat)
No FP for Haunted Mansion (waited 10 minutes), skipped Splash because we were already wet, hungry and a bit tired (we drove to DL straight from Las Vegas during the night). We had lunch at the Rockets place in Tomorrowland. Was good, we enjoyed. Used FP for Space Mountain, Ghost galaxy, thrilling, especially right after lunch
Hit Toontown, no FP for Roger Rabbit so waited 15 minutes to ride it, then met Mickey at his house before hitting IASW (no wait)
Left for DCA. Skipped GRR (same reason than Splash), waited 10 minutes for Monsters Inc, 5 minutes for Tower of Terror, little bit of shopping.
Finally got a FP for California Screamin, played a little bit in the boardwalk games, and waited 20 minutes for Toy Story mania. Took FP for Soaring over California. Had dinner at the Taste pilots, great ribs.
Rode California Screamin and we loved it, made our day. went for soaring after.
Shopping at Dowtown, went back to DL, Alice still wasn't operating, waited for the Halloween fireworks and walked back to the hotel, hands full of shopping bags for a good night sleep.
A great day that we really enjoyed thanks to all of you who gave me there advice for our short visit.
Thank you again
