The Revival is the best motor event I've been to and I look forward to it every year. It's sublime. Classic cars, automobilia, flying display, people watching. It's got it all.
I only live about 90 minutes away, and tend to only attend one day over the 3 day event. 4 of us hire a driver so we can have a drink or two (the driver plays golf while we party!).
You're travelling a long way so don't scrimp on cheap tickets. I've used 'The Mess' and can thoroughly recommend it. You get a lovely WW2 themed tent, with first class breakfast, lunch, tea, drinks, everything thrown in with your own table to come and go as you please throughout the day and situated right beside the track. The assembly area is adjacent so you'll get a great view of the cars just before they go on circuit.
As a bonus, The Mess has superb toilets, reserved for just for Mess pass holders - you'll be glad after all that food / drink and especially if your partner is fussy. Here you go: https://www.goodwood.com/hospitality...kuczdpcUAQ7.97
You don't have to wear period gear but most people do and you may feel disappointed with yourself if you don't. Military costumes are popular and easy but anything goes. I purchased some used stuff from a charity store - probably spent 25 quid on my outfit.
If you have any contacts with Bonhams, Rolex, or other sponsors - time to pull some strings. These guys usually run a slick operation at the event and if you can get in on their hospitality then good for you.
You'll have a great time.
