Cheltenham Race Course Station is the southern terminus of the GWR. The GWR's station is signposted from the the main entrance to the race course where there is ample parking for both cars and coaches. There is a GWR shop on the platform with lots of gifts for all ages.
Persons using public transport, route D, to get to Cheltenham Racecourse station are advised to walk the ¾ mile from the park and ride stop.
... but ¾ mile is a long way for those of fbb's advanced years.
An opportunity missed. Such a pity!
But there may be other options. We must investigate further.
