Yes,
DVC was specifically mentioned as one of the factors conributing to income growth at "Domestic Resorts" (which means theme parks and resorts).
Here's the paragraph from Disney's first quarter earnings press release,
The Walt Disney Company Reports Higher First Quarter Earnings:
Operating income growth at our domestic resorts was primarily due to increased guest spending and attendance, continued strong sales at Disney's Vacation Club and higher hotel occupancy. Higher guest spending was driven by increased ticket prices and merchandise sales at the theme parks and a higher average daily hotel room rate. Increased attendance for the quarter was driven by the celebration of the 50th anniversary of
Disneyland at both domestic resorts.
