I will be staying in Brighton for a few days this July, and would like to take the National Express coach to Hickstead for the Longines Royal International Horse Show. I am planning to go on the 19th and 20th of July. I can find the ticket on the National Express site, but I am unsure if I have to buy the tickets in advance or not. It appears that I am locked into a certain time if I do, and I'd rather not be.
There seems to be a coach every 15-30 min, so I'd rather just see which one works out on the day. I can see a way to buy an open return on the site, so if I have to choose an outgoing coach, I guess that would be my best option, as the return will be the hardest to predict, I think.
If I don't buy in advance, where do I buy the ticket? From the driver? The fares seem about the same when I put in my actual dates or today's date.
I've never used National Express before, and when I search I mostly get information about the airport buses.
Thanks for your help!
