Vivaldi Resort - 3D 2N doable

First timers to the ski resorts, first timers to enjoy / suffer subzero winter.

I am planning to for a 3D 2N stay at vivaldi resort, with 2 kids. according to the old-timers here, 😄 i understand that for ski-ing is not doable for 2 consecutive days as will get muscle sore and stuff, planning to get a private coach to teach on a family of 4, and i believe after the 2 - 3 hours session, high chances is nothing is learn. just a familiy learning and experience of fun and joy. So i am planning on 1 day ski, the other day will be sledging.

with this in mind, do 3D 2N still doable? or is better to take 2D 1N?

TIA.
