I have indeed played Aliante when in Vegas, probably 3-4 times. It's a very nice track and up North of town. It also has a few nice homes around it.
I won't give you advice on a home course, only because you really need to experience all the courses have to offer before deciding whay fits your needs. I'd never pretend to be an expert on all the courses out there either. I will say Aliante was a nice place and the people there were very nice. I also played Rhodes Ranch 4 years ago and found the people to be extremely friendly, so I'd go there as well.
Oner thing about Vegas... They are a bit pricey compared to the rest of the country. Seem to feel they have something special, in general. But you'll have a blast doing your research I'm sure!
