It looks like our winter trip will be a Universal Only thing. It just doesn’t seem worth “Disney money” for what would be a partial experience for us. No park hopping, having to pick a single park ahead of time, and no nighttime shows/limited entertainment just would feel too cramped for us, especially at Disney’s premium prices.
I’m also betting that Universal will offer some great package deals with the new properties there. With two theme parks plus Volcano Bay, which we adore, a nice relaxing Universal week actually sounds quite nice, versus the military precision that a Disney vacation will be.
