I know when I was booking my season ticket - I looked at a bunch of Palace club web sites, One of them, I think it was accessed through the Premium matchday experience's section had a link to the various views, especially the restricted views -

When I get a sec I will see if I can find it for you.

I have looked Jimmy - Either I continue to look in the wrong place or the link has been wiped out - possibly it was only there before the season started to aid those that were choosing season tickets -

Possibly the best thing to do would be to post where your wanting to sit & ask if anyone is sitting near there & what the view is like .

Sorry I cant be more helpful.
