Good idea on local sides marauder. Will be a little harder if any distance has to be travelled. The clubs do know what the cost of travel is before the season begins. I help run a side so we know our travel costs. What does place pressure on the club is cash flow. Our club had a trip to Wigan then 2 trips to Cumbria earlier on in the season. The three coaches were £2500 which i personally paid untill we had a few home games to pay me back. Not ideal but when needs must!!! We are constantly fund raising but again planned throughout the season so it's hard when fixtures are changed/amended during the season so constant revenue from your home games is crucial.
The cost of a coach in the summer is a lot more as well and they become like rocking horse poo if you can't book well in advance.
