With this year's megabonus giving a 1-night cert. for two stays, my wife signed up for her own Marriott Rewards account even though she never stays at Marriott by herself. This week we stayed at two Marriotts in her name as we moved our household from Florida to North Carolina. She got a cert that we both can use in addition to the cert I'll earn. Two certs for four stays for one couple. Sounds good to me. Has anyone else done this?
