Remembering there is no legal requirement for anyone to walk in with you, many people prefer to walk with someone who can support them during this time. As long as there is space anyone can walk you down the aisle.
Many brides/grooms choose to have someone special walk them into the ceremony space. Your Celebrant should work with you so you know your options, then you decide what is right for you.
