According to the publicly-accessible Llandudno U3A website, Yorkie, that is not how it works.
http://u3asitec.org.uk/sites/l/llandudnoarea/docs/localtheatreprogrammeapriljune2014.pdfI am aware of the group discounts for coach parties but when our eldest was teaching in a local secondary school, she also organised group bookings with group discounts for her students.
As for the booking fee, I do not pay this whenever I book tickets and nor do I pay any credit card charges because like many others I am a Premier Card holder.
I also receive a regular 10% discount off ticket prices as well as ‘two tickets for the price of one’ offers.
For anybody who is a frequent visitor to Venue Cymru and/or Theatr Colwyn then ownership of a Premier Card at an annual cost of £25 is a no-brainer.
For the record and as a disclaimer, I have no connection whatsoever with anyone involved with the theatre although I will admit to being a non-active, non-participating member of the Llandudno U3A.
