Is it one ticket per ST voucher? Going down on Wednesday am - just need to know how many vouchers I need to buy 3 tickets.... can't get thru on the switchboard. Might help if there was some PROPER information on the website instead of You need some stubs plus ST on Monday, we'll tell you how much it is when you turn up; You need a voucher out of ST book on Wednesday - you can guess how many tickets you're allowed to buy. (dunno)
It will probably be one ticket per criteria but it would be nice if the information given to us was clear enough.
