Currently I'm in the process of organising travel to Assen des nations, and am curious as to what viewing at the track is generally like. Is there much freedom to move around different areas around and on the infield of the track, or is everyone mainly located in one of the grandstands? Does the grandstand provide good viewing (is there any areas better than others), and for anyone who has been to the GPs there I assume grandstand seating costs extra?
Asking on behalf of a few family members who are attending but wouldn't be able to stay on their feet all day, and whether it would be worth their while attending to sit in the grandstand for the racing if viewing isn't great.
(apologies if something similar has been asked previously, couldn't find anything specific)
