I'm a plat and my offer is 25k after 15 nights, additional 10k after 20. I always get similar offer and always switch to certs. I'm a plat because of rollover, credit card, and booking rooms for a soccer team. I won't get close to 15 nights this summer. I guess I will switch to double points. Thank you, Marriott snobs, for complaining about certs and influencing Marriott to change. (Please note sarcasm)
