I'm optimistic too and have booked Snowbird Lodge late January 2022. Doesn't go non refundable until August by which time I hope vaccine situation will be clearer. Not getting any younger either so would like to go if its safe.
Still anyones guess. By August the vaccine program will be in its final phase - second doses for the youngest age groups - but the nasty P1 variant appears to have grabbed a foothold in BC, and it is vaccine resistant. April will be interesting.
