We understand that families grow and change! This can be done online by clicking here, or in person at your chosen attraction. Please note this can only be done at the time of renewal and not during the year and a maximum of two guests can be added to your renewal purchase.
For example, if you currently have Family of 3 Merlin Annual Passes that are due for renewal, and you now require a Pass for a child who has turned 3 years old/will be turning 3 years old during the validity of your renewed Merlin Annual Passes, and therefore requires their own Merlin Annual Pass, you can select a Family of 4 renewal.
