If you live or work in Cardiff, you can have free entry passes.
Usual cost of entry is £8.95 for adults, and £6.35 for kids. £7.50 OAP.
Save up to £16,244.25 for an adult!!!
As the title says, only if you live, or work in Cardiff.
This has been going on for years, but some people still are not aware.
Not expecting much heat, as it's such a localized freebie, but if just one family didn't know of this, then worth it.
