You're right about the tickets Mark. Another thing I remember about The Palace (big indoor fair) was the smell; a mixture of candy floss, chips, and machinery. Then there was that sort of high pitched siren which went off when one of the rides started. Fantastic place for kids and captured beautifully and honestly by Martin Parr.
Incidentally, Birkenhead band Rattlebus have written a song about it called Galloping Horses. It can be heard at http://www.rattlebus.co.uk
The fibreglass jets get a mention too.
