I currently have two DHS days planned. (My husband has not yet been on ROTR).
The first day, we are planning to either walk (we will consider it an "adventure") or maybe uber/lyft to... Contemporary I believe, as was recommended somewhere upthread, in order to make sure we are scanned (or whatever!) in.
If we get everything in DHS done the first day, then we will see about getting a reservation for a different park on the 2nd DHS day. And if we cannot change the park, or rope drop is not a goal, then we will try the Skyliner a little later that second day.
My sister and her family with three kids (including one in a stroller) is there now, at CBR, and they WERE able to get BGs both of their DHS days and used the Skyliner, but her first day they were considerably farther back. Today her husband got in the Skyliner line at 0715 (when it didn't start running until 9!) That's a long time to wait for it! But with little kids they could not have attempted the walk anyway.
