Radisson’s Friends and Family rate is a 25% discount and valid through the end of the year using promo code CARLSONF, according to this Flyertalk thread.
I don’t know any more about it than that, so I’d like to see someone report back on Flyertalk having used the discount before I use it myself.
I’m familiar with the Priority Club / Intercontinental Friends and Family rate which is usable by anyone and the Fairmont Friends and Family rate which requires a ‘booker ID’ (basicaly an employee number) but not other verification (there are several employees on Flyertalk who make theirs available).
The Marriott Friends and Family rate requires a rate authorization form signed by the sponsoring employee’s supervisor. And Hilton will give anyone 25% off just for using a Visa Signature card so don’t really need a Friends and Family rate there. (They probably offer a friends and family discount but I don’t know the details.)
These offers are all different. Bottom-line is every chain makes discounts available, not really as a “friends and family perk” but as a way of generating price-sensitive incremental revenue. Using the narrative of insiders it’s a way of separating these out from regular bookings and not leaking revenue from higher-priced reservations.
Makes sense that Radisson would follow the lead of other chains who have generated incremental business during a downturn this way. However I’d want to know whether anything else is required of the guest besides entering a promo code before booking.
