It depends on the club Mav, if your meaning what i think you are - You can send them just as trainers providing the club permits it - Around our way though you tend to pay the same - Would be much easier for you to join the club though as for what you pay you will get the chance to clock and also other little extras such as distances etc.
As well as that you would have to be a member of the RPRA to send trainers regardless so joining a club is defo the easiest way.
If your along the other meaning and that is just to enjoy the birds and relax whilst waiting etc on a race day .... Yeah defo, nothing can beat sitting in the garden on a nice day with some beers and friends around to watch the birds also.
