Sheraton Vistana Villages - yes/no as I have some concerns

Ok, right off I%26#39;m impressed with the look of these and also what they have to offer.

I%26#39;ve read some great reviews and not so great. I try to take bad reviews with a grain of salt b/c this is still rated very high according to trip advisor.

My concern that I have recently read about is smoking rooms. We are non smokers and greatly prefer non-smoking rooms. Has anybody had any problems with this?

The other thing that I was wondering about was the different Villas they offer. There is the Amelia, Key West, and Bella Florida. Are any of these better than the other?

Thanks
