I know it's a loooooooooong way out, but i've just booked a tent for the Cup. Surprisingly really good value, weill in my opinion it is.
Tent- $495 for 10, $25 for every person after that (Minimum of 10, maximum of 30- I think 20 would be ideal)
Bus- $400 (21 seater work bus through work)
Beers (coopers only) Full strength slabs $65 Mids/Lights slabs $55
Free race books
All drinks on ice in tubs in your tent.
The way i look at it, it'd be $25-30 to enter, Beers would be the best part of $10 each, Race book $7-8ish and bus trips vary from $30 to $50 return.
Booked Thursday and Friday off as i know how this ends.
