Thanks for those posts, Nick and Lee.
Some thoughts ...
a) "Retired" fares. So not accepting senior bus passes. Saves council money
b) 5 week trial / up front season tickets only (in effect). So not effective for casual / occasional user
c) 5 week trial / up front season tickets only (in effect). So how will they market it after the initial splurge?
d) Presumably non-transferrable tickets. How are they going to check ID?
I'm sure all of these things have been thought through .... just that I don't know the answers.
