Typically redemption rates are room only and people rely on their status benefits, if any, for breakfast.

There are some hotels where this won't apply, and breakfast is included as everyone gets it when booked through all channels:

• Where the brand offers everyone "breakfast" (see this list here: https://www.nerdwallet.com/article/t...8-major-hotels which I think is accurate): Residence Inn by Marriott, SpringHill Suites by Marriott, Fairfield by Marriott, and TownePlace Suites by Marriott.
• It could be any hotel, but I see more for Autograph or Design hotels where it is part of the standard offering in their country - this will be specified in the rate details, explicitly saying "breakfast included". More likely to be international properties
• For a very small number of all inclusive properties where your points buy the whole package
