Barry Island Pleasure Park
Vale of Glamorgan
There are a few public transport options to avail of but most visitors will likely have their own mode of travel. Take a look at car rental options plus for those who want to try something different there is https://www.convertiblecarhire.co.uk/ who offer convertible sport and luxury vehicles.
Try to get a car with a sat nav if possible as you may be visiting other parts of Wales and it can certainly come in useful.
