Didn't change anything for us! If anything it made the park hopping we do easier!!
Usually our last day is 3 of the 4parks, so we'd do this:
-Rope drop AK, hit up headliners
-Hop to DHS, where we'd pull a fast pass, and then wait around in long standby lines
-Then hop to MK for the evening
With fp+ we now hop to DHS midday and walk right onto all the rides we want, with a guaranteed fast pass!
