Your Sales Executive can set you up with rooms etc. Whether they can do more than your offers, I can't say other than I always ASK if I want an extra night or a particular upgrade, help booking a meal or show, etc.
Caesars has had this for quite a few years, using persons with that type of title. My current one is "Entertainment Executive" or something like that. Always had a positive experience with them.
I recommend e-mailing that "Sales Executive" with the offer from the web site, give all information including offer #, and anything additional you would like (extra comped night, certain tower, Strip view, etc. Tell him "This would be my first trip to Vegas, and would love to have a Strip view if possible."
They don't guarantee towers or views, but it will be noted on the reservation and you have a good chance of getting it.
