Just a heads up - I had things booked with laterooms and the advice seems to be to contact your accommodation direct and check everything is OK.
One of my booked places has been told my card isn't valid and to check with me.... but my card is valid it's just that laterooms can't hold that information anymore or something.
Laterooms are just a broker and haven't taken payment so it seems all is fine and bookings still there but you might prefer to check.
Never used superbreak so not sure about them but they are part of the same group. Good luck all.
