Apple is offering cardholders immediate access to Booking.com's Genius Level 2 after one qualifying stay or rental car booking. It is important to note that Genius levels are unique to Booking.com, and not to Apple Card. In addition to discounts and perks, users who book via Booking.com with Apple Card will earn 3% Daily Cash. It's not hard to find a hotel that offers free breakfast without the Genius Level 2 perk level, either. Truthfully, the biggest reason to use your Apple Card over, say, any other rewards card would be the 3% Daily Cash and the 2% Booking.com travel credits.
