i did queenstown for a week last summer and it was awesome! originally planned to go boarding for only 3 days but ended up doing 5 in a row.
met a bunch of ppl in my hostel who was working there for the winter season while snowboarding at the same time although i was only there on vacation.
i had joined a tour while i was there that included lodging (hostels up to hotels.. depending on budget), lift ticket, rentals, and lessons. lots of tour places in town that also offer lift ticket/bus transfer up to the ski fields. gotta shop around for the best prices.
