I would like to earn points with Star Alliance. Regarding Hotel and Car rental point partners, do any of the specific airline programs (United Airlines, SAS Scandinavian, Air Canada, etc ) have hotel point partners with:

- Club Carlson (Radisson)
- Choice program (Quality)
- Best Western

Also, do any of the specific Star Alliance airline programs have car rental point partners with:

- Avis
- Budget
- Hertz

Any recommendation on which Star Alliance airline program I should focus on?

Thanks for your help!
