Exeter eh? I'll have a look. Watch this space.
Edit: You can go by coach for £16 return. It is a long journey however but I will post the details. (Note that this is for the weekend 5th September to 7th September. October is not bookable yet).
5th September
Depart at 02:45am Exeter - London. Arrive at 07:00am
Depart at 08:00am London - Leeds. Arrive at 12:15pm
7th September
Depart at 17:00am Leeds - London. Arrive at 21:45pm
Depart at 23:00pm London - Exeter. Arrive at 03:15am
I know its a dodgy journey but if the price is an issue, all 4 coaches only cost a combined price of £16.
I have done journeys worse than this before.
