Site night vouchers

guys n gals

is there any other way of receving the site night vouchers from the club? i know you receve them by getting the credit card and earning points but  i dont want the credit card i do not possess one and am not planning on getting one eather. so i was wondering if there was other ways to get them?  also thinking about it what if your credit status means you carnt get the credit card you will also be penalised and not be able to get the vouchers. i stay on the cc club sites for approx 50nights per year this year i have about 60 nights booked so a free night wouldnt go amis 

cheers
