Current user fee for climbers on Denali and Foraker is I believe $365. Part of the reason for the booklet you linked is that many climbers (often but not always foreigners), who may be highly experienced in other regions, arrive somewhat unprepared for conditions on a 20,000 ft peak located in subarctic latitudes. I believe the NPS relaxes some requirements slightly for climbers who have been on the mountain previously, on the assumption they have a better idea what they are getting into.
