The 30/12 to 02/01 I'll be not far from Liechtenstein and I would love to discover 
But it seems quite difficult because I can't find any transportation the 30 and 31. 
Do you know why ?
If your a traveller near (Bodensee) Lake Konstanz or Liechtenstein I would love to meet you ( discover some places, have a coffee, talk etc ) 
There are no trains on weekends in Liechtenstein. International long-distance trains go straight from Buchs SG to Feldkirch.
However you can take the bus from either station (running every 30 min). A full-fare day pass costs 10 CHF from Feldkirch, 7 CHF from Buchs SG. Check (and buy on) SBB app.
