We stayed at GF Aug 2014 & Poly Aug 2015 and both trips monorail was on a modified schedule

. We had to work around it. Mostly busses to Epcot in the morning. Last Aug schedule was more confusing. Really had to read the schedule every morning. One morning we walked to TTC to catch Epcot monorail, oops. Not running that morning and ended up having to take a bus we could have caught at Poly bus stop.
Monorail issues just keep going on & on. Seems no end in sight. This August back at GF, hope it's back to regular schedule by then.
