Family of 4 (2 adults, 2 12yo) travelling from Wengen to Montceau-les-Mines station in France this June. Is it worth trying to incorporate Golden Pass Prestige from Interlaken to Montreaux for this leg of the journey? Is it worth it to try to incorporate it? If we opt to do it, how much time should I allow to switch from SBB to GP in Interlaken? Is there a better station to catch GP rather than Interlaken on this route??
Finally- if our time in Switzerland will be spent ZUR directly to Wengen then on this path, is half pass travel card the best option (the 2 kids would ride free) or another option better?
