So happy you get another Vegas trip! You should email your Cosmo host and specifically ask for the room you want. Hosts will always book you lower than you qualify for if you don't ask. (I know this from experience and it's been confirmed by several of my hosts). They will assume you are happy with what you had. So send her/him an email and say you are hoping for a (whatever you're looking for) if you qualify. Your host will let you know either way. I'm sure you will get what you had if you don't specifically ask. They are used to negotiating so will be honest with you either way. Can't wait to follow your TR!
