Normally I would suggest this but for a couple reasons I didn't.
This year DCA is opening it's new entry and a new land, Carsland. When is not exactly known only that it's be open in the Summer according to Disney marketing. When CL opens it is sure to mean bigger crowds.
Some are also speculating that as part of preparing for this Summer's new attractions, that many other parts of the resorts will receive rehabs. It's always been common to do some rehabs during this period that have affected major attractions for a week or two to get them ready for a busy summer. The only thing now known is that Matterhorn will be down through the 14th of June, and GRR and SoC are getting pre Spring Break rehabs.
