We were at WDW last summer but we skipped DHS. (Each year we skip either DHS or AK in order to have more, leisurely MK and Epcot days.)
So actually it has been since 2012 at least since we were there. Did a lot close between 2012-2013 or were most of the closures in the last year?
Seems like they would plan these things better..as in build new before closing old

. Otherwise people just stop going there...
