Never been to the bonfire, but we stayed near Lewis for a week last year. Nice part of the country and I played West Sussex and Royal Ashdown Forest while we were there - both well worth a visit. Rye is also in striking distance and you could easily combine with a trip to the Kent links as well (Royal St George’s, Deal, Princes).
As for the weather at that time of year - it’s pot luck really. Certainly won’t be warm, but if you get a dry week it can be a great time of year to play. The links courses would certainly be fine.
