Right need to get peoples thoughts on this.
As some people want to go Rayleigh to the indoor.
Some don't like indoor and would like to do outdoor racing.
So I will go with the general consensus of what people want to do and how much they are willing to spend.
There is some choices I have shortlisted.
Rye House Karting Hoddesdon Hertfordshire- Outside Track, Twin Engined Pro Kart.
- 15 min Qualification,
 
- followed by a 40 min race,
 
- Price is £85 but can be split into pairs @ £47 each.
 
- Or they do a Le Mans Event,
 
- Practice then a race for 2hrs for teams.
 
- @ £190 per team. Team size 2-5 drivers.
 
- A team of 4 would cost £47 each. 
 
- No Mininum amount of Drivers

Personally I like Rye House Karting. 
I'm not a huge fan of indoor circuits but that's my opinion.
