There's always another way. Maybe not a *pretty* way....

  ^PER NIGHT [ONSTARIG]{2,8} [0-9]{1,2}\s?[A-Z]{3}[0-9]{0,4} FOR (\d{1,2}) NIGHTS?$

The downside of that being that it could match other words besides ON or
STARTING. You could use [A-Z]{2,8}, but that would have even more
potential for matching unwanted words.
