DN bonus: 2500 points for lounge closure
FAQ:
• T &C: 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 entrιe (or standard breakfast buffet), juice and coffee (tax, gratuity and service charges included) for each registered guest in the room, maximum four (4) people.
• So….
1) Denied access to open club - full breakfast in restaurant + 2500 points.
2) Temporarily closed club - doesn't matter if it’s seasonal or day of the week (e.g. closed on weekends) - full breakfast in restaurant + 2500 points.
3) No club at property (or permanently closed club) - full Breakfast in restaurant, NO 2500 points.
• It's not really a property discretion issue about the 2500 compensation points but Corporate CS will verify with the property that the RC/GC that is usually open was indeed closed on the date of the stay.
• 2500 points per stay, not night (including if you have a long stay covering 2 separate weekends)
• If closed for any part of your stay, even with breakfast vouchers, you are eligible. e.g., if closes Sunday after breakfast and reopens Monday, guests staying on a Sunday night are eligible for the 2500 points.
• Some properties are good about posting this (HR Schaumburg) while others (HR Milwaukee) are not. May require a call on the Diamond line
• The bonus (in lieu of lounge access) is a Diamond benefit so you get it regardless of how you paid (points, cash&points, My Elite rate, corporate rate, Hotwire/Priceline,etc)
• DISCLAIMER: The times (months, days, hours) of lounge closure may fluctuate. Please take what you find here and verify with the property if a closed (or open) RC/GC is important to you.
