This is true for us, too. We also took a cab from Animal Kingdom and Hollywood Studios. Cabs are already there. I don't know if this will change when Disney Springs is completely done, but in November we took a cab from AK to DS. The drop off was near Cirque du Soleil. It was a long hike to Market Place where we wanted to be!
Cabs will now be a part of our trip
budget - especially if we stay on the monorail again. While there is easy access to MK and Epcot, getting to HS and AK takes a LONG time including waits and stops at other resorts. The same is true for Boardwalk and getting to MK, AK and Disney springs.
