This year’s Pilgrimage to the Apple Headquarters at 1 Infinite Loop in Cupertino is of the DIY variety. In past years Apple would have updated the Company Store website with information about extra opening times for WWDC tourists, but this year they didn’t.
Traditionally there were several busses organized by Scott Knaster. I don’t know if his reason for not doing it this year was lack of a WWDC ticket or lack of confirmed opening times. Either way his professionally organized tour did not come to pass this year.
