Yes, all lift tickets from 2 day to 7 day must be used on consecutive days. 8 day to 14 day lift tickets allow for two rest days. I.e. an 8 in 10 day lift ticket is valid for 10 days from the date of purchase and you can ski any 8 out of those 10 days. All 15 to 21 day lift tickets allow for three rest days.
