I'm a Disneylander. I went to WDW the first time in 2016. We spent a week with at least 1 day a park, and we still did not see or do everything that is to be done. When I plan a Southern Californian adventure it is just that. We usually spend two or three days at Disney, and for cheaper in a non-Disney hotel. The biggest difference is that it is a Californian adventure. We would have a day at Knotts's Berry Farm, a Day at Universal, A beach day. Now My wife is a fly down and usually stay at a DLR area hotel and drive to the other places. In my youth, my family would road trip from Seattle. So, it would be the parks as Icing after going to Reno or Vegas, Yosimite, Redwood, San Juaquim Valley, San Fran, Deigo. When you do go to DLR for 2-3 days you pretty much can see everything in that time. Character Dining vouchers are good, but meal vouchers is a loose. Many of the passes ans attractions are first come first served the day of. Blue Bayou is a must, it was first come first served for reservations, but I am told that has changed. It has been some time since my last DLR trip. I have not been to DCA yet, so you might need to go 4 days. Even if you have a similar ride at WDW, you still need to ride the west cost version.
