Kate Stevens described her 11-year-old son, Jacob, who has Autistic Spectrum Disorder and ADHD, being left in tears after their planned Christmas outing was cancelled.
Neon, the event creators, and Wowcher have both issued apologies, with Neon offering alternative sessions or full refunds, and Wowcher processing full refunds for affected customers.
The incident occurred at Neon's newly opened venue within the iconic London landmark, with Wowcher attributing the overbooking to a system error on Jurassic World's side.
