Looks like you are a WDW vet. Before you make your decision, you need to understand that hopping at DLR is nothing like hopping at WDW. We are WDW vets too. For us, DL/CA are like one park. We go back and forth all day. You can get from the back of one park to the back of the other in 10 minutes. The parks are only separated by a plaza. You do not have to go through bag check to hop as back check is at the outside edges of the plaza and is for both parks. It is literally less distance than walking from most bus stops to a gate at a WDW, to walk between the parks at DLR. There is no time investment in hopping and it is simple to go between the parks repeatedly during the day. I don't know what the hours are when you are there, but there have been times we have been there that CA opens later or closes earlier than DL. Rope drop at DLR is less crowded than WDW because a lot of the crowd is local- the first couple of hours are terrific most days. We would go to DL for the hour or two they were open before CA and then hop to CA at opening to hit some things there before the lines built. At night, when CA closed, we would hop over to DL. Also, we will look at the wait times app-- if we are in DL and the lines seem long, we will look to see how the lines are at CA-- if they seem to be much shorter we will go over there for awhile and take advantage of the shorter lines. If DD suddenly decides she really wants to ride something in the other park that day, we simply go over and do it. If you google map the parks, you can get a view of the plaza and see how close the gates really area. Hoppers aren't necessary, but they are very useful at DLR.
