We're planning to avoid the parks for a couple of years because there are already talks about 8 hour lines once SWGE opens. That's even before the hotel is built.
Also, keep in mind that there still isn't an official opening date - we know things are on track now, but while a late fall opening next year seems likely, LOTS can happen with a huge project like this. That is just to say, if the only reason you'd be doing the jaunt to WDW would be for SWGE you may want to have a plan B in case the date gets pushed, or the ability to enter the land is unlikely due to crowds/ticketed events/exclusive events.
