Yes with HGVC timeshare 'points are points' and can be used anywhere within the HGVC, but if you buy 7000 points from one resort and 5000 from another remember that these points are attached to a deeded week at the home resort, a specific county/state and therefore each will have independent maintenance fees and taxes.
I advise buying HGVC timeshare at the same home resort, a resort with low annual dues and trading for other locations with hilton.
Hope this helps and hope this made sense
