4.0
Pros: Over all it's easy and nice. Both train and bus has bathroom. Cons: 1. At train station it's very confusing to find the correct track to get on train. 2. Bus seats are very narrow/small. Tips: Need to arrive early to find some strain station staff to ask which track to wait for train. From Sac to Tahoe some area the road is under construction, expect some waiting time(adds together total 40-60minites).
