After talking to one of the women who runs/helps out at the ballroom dancing classes, it appears there is another class in Wendover at the Memorial Hall.
This starts at 7 pm, which is a little more sensible and costs £6 for the hour. However, it is possible to add some social dancing on afterwards. This is from 8 until 10. although this is an extra £1:50.
If you don’t need the lessons then it is possible just to do the social dancing and this costs £3.
As the sticking point for progress on the way to becoming a genuine “Strictly” contender is the practice required - then this should help you greatly.
