The UK engineered and developed VQ2020 system from Lo-Q uses wireless handheld "Q-bots" to enable users to join virtual queues, freeing them up from standing in line.
The virtual queuing system means every visitor will still have to wait the same amount of time for rides, but they will be able to spend the time doing other things.
"Our park is aimed at the under 12 age group and they will especially enjoy having Q-bot wait in the queue for them," said Vicky Brown, general manager at Legoland.
The system was trialled at Thorpe Park, which belongs to the same Merlin Entertainments Group as Legoland.
The VQ2020 system is in use in three North American parks, with other Lo-Q systems in use at six US theme parks and four in the UK.
