We will be open daily through the East Sussex school holidays.
It really helps us if you book in advance through this website (PayPal required) as we are still carefully monitoring visitor numbers, and controlling session availability in line with employee availability.
Online booking closes at 23.59 on the evening ahead of each date. If you miss the deadline, or don't want to use PayPal to pre-book you can pay on arrival; but please check we are open and call ahead before starting your journey...
