So Cal to Harrahs Tahoe best route when snowing/reno tahoe shuttle service

Just wanted to see what others prefer when driving from So Cal to Harrahs Tahoe when it's snowing in the Reno/Tahoe area.

We live just north of Los Angeles, so my 3 choices are
395 past Mammoth etc.
5 up to Sacramento and then up 50
5 up to Sacramento and then take 80

my thinking is 80 is probably maintained better than 395 or 50, but my boss skies and has a cabin in South Lake Tahoe and prefers to take the 395 route.

We have chains and husband knows how to drive in the snow.

Other question regarding shuttles/buses running between Reno and Harrah's Tahoe. Due to husband's free play and gift card being at Harrahs Reno and my free play being at Tahoe, he needs to either drive to Reno from Tahoe or take a shuttle. If roads are clear, he'll drive, but I'm thinking it might be worth the $ for him to take a shuttle if it's snowing. Unfortunately each of our offers necessitated an overnight stay to get the free play/gift card. Do the shuttles run when it's snowing and anyone have a preference?

The concierge at Harrahs Lake Tahoe told me if the roads are open the South Tahoe Express will run.

I'm thinking both the 50 and 80 would be well maintained as both are key routes from the bay area and Sacramento to Tahoe/Reno. Wouldn't there be greater chances of ice patches on the 80 due to the bridges?

Good thinking, those bridges do stay icy a while on 80. Right now with a week to go weather report looks good for no snow driving while we're in the Reno, Carson City, Tahoe area.
