Leisure Vouchers - anything clever to do with them?

Witham

I've got £100 worth of leisure vouchers (leisurevouchers.co.uk) and (at risk of sounding a right old bore!) I'd struggle to spend them on anything useful. Apart from extracting the maximum value by spending them on discounted offers etc, any suggestions for maximising their value or turning them into cash or a cash equivalent?

Depends on what you would enjoy. Is it one voucher for £100 or vouchers adding up to £100.
Premier Inn have a promotion on at the moment if you fancy a weekend away somewhere (from £29 a room) but you would need to T&C's that you still get that rate if you use vouchers. Then you could use some for meal as lot's of eating places take them, or buy something, Halfords/Waterstones/HMV, if there isn't anything you want ask family & friends if they are buying anything from these shops could/would they use some of your vouchers & give you the cash?
