Chessington World of Adventures will offer previews of its new World of Jumanji area to Merlin Annual Pass holders.
On 14 May, the day before the area opens to the public, pass-holders are being offered access across two time slots.
The slots are 13:00-15:00, and 15:00-17:00. The slots will be available to book from 3 May and 6 May respectively.
Merlin Entertainments said that links would be posted on social media at 12 noon on the above days.
The World of Jumanji will feature the Mandrill Mayhem rollercoaster, plus two supporting flat rides called Mamba Strike and Ostrich Stampede.
All rides will be open during the previews, with winners of a previous competition being given access access earlier in the day.
