Fame costs (so do sports days). And right here is where you start paying.

Event	Details	Cost per head
Go Karting	GP (not mentioned on their website) 10 mins qualifying gives your grid place for a 20 min race. All stats printed out at the end.	£45
Golf	Chessington Golf Course	£12.50
Bowling	Hollywood Bowl Tolworth 2 games inc shoe hire	£11
Afternoon	Unknown but if it’s Table Tennis	Free
Pool	If everyone plays everyone won’t be more than	£5
Darts		Free
Quiz		Free
Food and water	We’ll sort out on the day.
Total	Rounding off to	£75

This is just to give you an idea. I'd like to keep the budget under £100 but if Go Karting is not seen as good value for money we're looking at £50.
