Hey OP, I’m sure you’ll have an amazing time. The skiing is a bit more challenging than Sunshine/ Lake Louise etc and I did feel that but you’ve got much more experience than me so I’m sure you’ll love it!
The restaurant at the top of the gondola (Eagle Eye) has the most amazing views. It’s billed as fine dining and whilst it might be in the evening, it’s a lovely lunch place and really family friendly too. It was a tiny bit more expensive than the pub/ restaurant at the bottom of the gondola but well worth it. I can recommend the cheesecake 😉 it might be worth popping in to book a table By the window if you can. We waited for about 10 mins without booking.
If dc is interested in animals / wildlife then you could learn a lot about Boo the bear. The slopes go right round the edges of his habitat and his den is right in the corner so you can see that (quite cool to know he’s asleep about 30 feet away from you)! There’s an interesting history of why he’s there/ the conservation lessons learnt/ his escape a few years ago etc/.
We stayed in the one of the hotels at the bottom of the gondola so can’t comment on Golden, which is 15-20 mins drive from the bottom of the slopes. I can recommend the Copper Horse Steak House for dinner (near the gondola) but it might not work for you to eat away from where you’re staying. If you want to eat before leaving the slopes then Winstons was great. Fab food (try the winter salad), big fires, and lots of games for kids inc giant jenga, dominoes, chess etc.
You’ll be about 2 hours from Lake Louise I think and if you want a day off skiing it really is a gorgeous drive and then there’s ice skating on the lake itself/ an ice bar serving fresh maple syrup lollies etc when you get there. However, I don’t have dc so that length of drive may not be practical!
I absolutely loved it (can you tell?) and would go back in heartbeat. Have a fab holiday and do come back and tell us all what you thought.
Oh and we had a real cold snap when we there (-30). In case you have the same: we layered up but the one piece of kit I wish I’d had was some boot gloves. They’re c$40 I think and everyon I spoke to who had them swore by them.
