I am sorry I can't help with time - that would be dependent on the race times. Parking is easy, but obviously there is a limited on how many people are visiting. Main parking areas are quite close to the entrance. Search following for details: cheltenham festival parking map

Something warm, other than that I would suggest that anything reasonably smart would do - this is not Ladies Day - this is just a meeting and I guess there is no real dress code applied on a early spring day but the cold wind and good chance of rain will dictate warm and wet gear.

If you take a look on the Google satellite images of the area near to the A435 and the B4075 you will see that the area has a fantastic infrastructure for vehicles. I would guess that you will be dropped-off near to the Centaur wher most of the bars and hospitality suites are situated. They are unlike to drop you in the centre of a field because they want your money not your complains. I would contact National Express and ask them where the drop-off and collection points are then you can find them on the site map. See how to get to cheltenham racecourse on Google

Tattersalls for festival trials day - you get the paddock area and far more facilities

I think if you can get it in Eat it..

Club enclosure tickets also give you entry to the Centaur Bar where there is a lot of seating and also where the bands play after the meeting. Gets very busy but lively atmosphere. Hope this helps.

Sorry to be late March is the time for queues the other meeting are busy, but you are mixing with some of the best people in Jump Racing..

Sorry don’t know name but I know where you were ...I would suggest you go at least 2 hours before the first and park there again ...I find these spaces are a premium because you will always be delayed in the course official areas ..good luck I say 2 Hours because I always use 3 hours and spend an hour in the car to catch up with the form in my Racing Post ..enjoy

Yes, great viewing area!
