2 During periods of high demand access to the Regency Club or Grand Club lounge may not be available; therefore Diamond members will receive 2,500 bonus points per stay plus daily complimentary full breakfast inclusive of one entrée (or standard breakfast buffet), juice and coffee (tax, gratuity and service charges included) for each registered guest in the room, maximum four (4) people.
This is nicely ambiguous. If you don't get into the lounge because it's full, you get the benefit. But it doesn't say that if you don't get in because it's closed you get anything.
