I'm sorry I'm just not a fan of this whole area. Waaay too many tourists and not the cleanest part of the city. While it offers great views I'd skip on a short trip.
Spent a whole day here and could have spent many more. It's not cheap and there's a lot to see so I would start early in the day. The crown jewels are just incredible and everything is displayed so well.
If you're staying in South Lake Tahoe, you'll want to ski Heavenly... it's on that side of the lake. On the north side, you'll have Squaw Valley and some other smaller mountains too.
