힐튼 골드티어 무료조식 rule이 바뀌었나요? (DoubleTree by Hilton Hotel Sukhumvit Bangkok)

제가 조만간 방콕 저포함 6인 가족여행이 예정되어 있고, 수쿰빗 더블트리로 숙소를 잡아놨거든요. 근데 제 티어가 다이아 였다가 며칠 전에 골드로 내려갔어요. 저 외에 다른 1명은 continental breakfast로 커버가 되고, 나머지 가족들은 얼마가 차지될 지 이메일로 문의 했더니 

"Regarding to your email as per below and regarding to your Gold tier benefit, In case of breakfast is required for other 5 persons, we would like to offer you with our special rate for breakfast cost is THB 471 inclusive of 17.7% of tax & service charge, per person per day (from the normal price is 660 inclusive of 17.7% of tax & service charge, per person per day). You can pay this directly to our hotel upon check in."

이렇게 온 것 보니, 저 말고 다른사람들은 다 차지가 되게 답변을 주었더라구요. 힐튼 홈페이지를 참고하면 (http://hiltonhonors3.hilton.com/en/explore/benefits/index.html)
