We boarded Iona just over a week ago. My daughter had a 12.30 boarding time but mine was 1.30 because we had booked seperate cabins as there was no single supplement . We obediently turned up at 1.30 (advised to turn up at later boarding time) only to discover that nobody even looked at our boarding times and everybody was boarded in order of arrival. Actually it was not too bad as we were through and onboard in about 40 minutes from getting out of the taxi. However, I suspect that if we had rocked up at the earlier time we would still have boarded in order of arrival.
