Micro sites are separate from your primary domain. If you want to target Region Golf, Region Dining, Region Events, you domains should be submitted something like this:
This is one site.
www.regionalsite.com/ <- primary
www.regioanlsite.com/Region-Golf <- page 1 with key (build diverse links using "regional golf")
www.regioanlsite.com/Region-Dining <- page 2 with key www.regionalsite.com/Region-Events <- page 3 with key
In this case you submit you sitemap to Google, listing all your pages.
This would be a micro site:
www.RegionGolf.com
The domain is completely different f rom the micro site. No association with www.regionalsite.com/, so it can not be included in the sitemap.
