I think you are right to be a little concerned. Ordinarily the chances of a non-holiday February weekend day filling up right when Reservations open up, would be slim. But with Rise Of The Resistance opening, it could complicate things. If it's available, I'd probably book Saturday first, and then the next day, Friday. Saturdays "usually" fill up first. My guess is that you will be o.k., but you should be able to get a good idea for when Reservations open in December for the 1st weekends ROTR is scheduled to be open. If those 1st Saturdays fill up right away, then you may need to be concerned. Theoretically CA Adventure should not be impacted by the ROTR mania, so hopefully you could get a reservation there, even if DL was unavailable.I know there have been very limited "Reservation Unavailable" dates so far, but the Rise of the Resistance opening has me a little concerned that this otherwise low-demand weekend will be unexpectedly popular. There are three weekends before February 8/9 for pent-up ROTR demand and President's Day the following weekend (which I assume will be more popular). The odds are really low that we won't be able to get reservations for February 8/9 weekend, right? Since February 10th is a "good to go" day for both parks, I'd be happy enough if we can get at least one of the days as "both parks" and the other just for DCA.
