Yes, i was going to respond to Sam mentioning that i was planning overnight at Domodossola (I) but this is a brilliant idea to consider,...
Of course, the total journey will be close to 7 hours from Milan to Wengen(day 1 - 4 hours + and day 2 two hours and 36 mins...
In my option, bus to Domodossola (I) from Milan was 2 hour 20 mins, overnight in Domodossola (I) and then following day 7:45am, take the regional train etc for a total of 3+ hours....
So, the two things i need to consider are:
Save myself the hassle of train changes and avoid the bus journey to Domodossola (I) with the Lucern overnight option... This will come at a cost i assume since i assume the BORP pass will not work on these EC trains and also a slightly more expensive hotel stay in Lucerne(let's say a total of CHF 200 CHF) but a clean option
The other option is Domodossola (I) overnight at a lower cost and following day tickets are covered in OBP and so, likely a savings of 200 CHF)
The current plan was to buy the four day BORP from aug 19 to Aug 22 when i return to Lucern before my flight out of Zurich on August 23rd
but, yes, i am tempted with the cleaner Lucern option as that can be peace of mind and smoother experience for my family i guess?
thanks
