Why not go for the £25 ticket? Lasts for....25 visits and it's not got date restrictions I believe. Or get the 50 or 100 visit cards? Honestly, work it out for yourselves - if you normally stay more than 4 hours every time you go, on your 3rd visit you would already be well into the money-saved scenario as 2 visits per the new pricing regime is £24 i.e. pay £1 more and have a further 23 visits. Even if you went 8 times for an hour or less we're talking £24 with these prices...the season ticket cost £1 more with 17 more visits allowed! Then add in that there's no charges for passengers in the car and you can see how getting the season ticket is good value.
