According to their terms and conditions (emphasis mine):
Changes in the route, date, time, passenger numbers or vehicle types
for non-promotional fares are subject to availability and will result
in the difference in price between the original price and the fare
applicable on the day you make the amendment being charged (a
“Re-price”) and an amendment fee as set out in the table in 4ii below.
You’d be charged (for the whole booking, not per person):
£20 + Walk up fare (at least £95) – Amount already paid
However, the risk of this being enforced seems slim, but if they tried it on, you’d have no recourse other than to pay.
