Oakwood, Pembrokeshire, trade 'boosted by new rides' A theme park which was hit by a second power cut in just over a week says its business is booming compared to last year. Oakwood theme park in Pembrokeshire apologised to visitors after a number of rides were put out of action for a time last Friday. The park, which attracts thousands of visitors a day, said its turnover last week was 70% up on the same week last year. But one visitor whose trip was cut short by last week's power failure says she is seeking a refund.
