Received an email from Mt Hotham with a 4 day any day lift pass deal. Seems pretty good to me if you already plan to go 4 days, don't want to be locked into a single time period like a consecutive day pass. You can use this at both Mt Hotham and Falls Creek lifts.
Passes are $369 when you top up an existing card without insurance, $5 more for a new card/account, $40 more for insurance.
Offer ends 28th Feb 2018 and lift passes are for 2018 season.
Note: These passes don't allow free skiing/snowboarding the night before.
No night before skiing with these, although this is a great deal, thought that was worth mentioning
