I have the Premier, not Prestige, but it also earns 3x at hotels, and I've always earned 3x on hotels booked through Booking.com or Travelocity.com, but they were only booked through those channels, they were "pay at the hotel" reservations, and thus the payment was to the hotel, and that's undoubtedly why it counted for the 3x TYP.
So it shouldn't matter who you book through, it matters who you pay. If you book some advance payment rate that's paid to the booking agency rather than directly to the hotel, then it might not count. but if you pay at the hotel, it should count no matter who you used to book the hotel.
If it's not a hotel / motel, then it might depend on exactly how it's categorized. And then the exact card might matter, because Prestige based on the list posted above just does certain travel categories, while the less-expensive Premier promotes itself as the card to give 3x on "the widest definition of travel" (for example, it can include camping sites if they code as such) while it's not at all clear if Prestige goes anywhere near as "wide' with "places to stay" as Premier does.
