Am planning my itinerary - would like to visit Garmish-Partenkirchen but can only squeeze it in towards the end of our trip, which means travelling straight to Munich Airport after that to catch our flight to London. The Munich-LHR flight is scheduled for 1330 hours. Since GaPa-Munich Hbf is about 2 hours + Munich Hbf-Airport is about 45 mins + allowance for change of trains (1 hour??) = 4 hours, and say we need to arrive at airport latest by 11:30, I should depart GaPa latest by 7:30 - would that be correct?
Will we need to leave even earlier, taking into consideration that we would need to change trains (and working in a comfortable 'layover' for change of trains, ie not having to rush from one platform to another within 10-15 minutes). I read in one posting that if I missed 1 of the regional trains there would be a 2-hour wait for the next one?? Will there be trains leaving GaPa for Munich at 6-7am (since they are regional trains, my concern is that they might not be that frequent, especially on a Sunday).
I tried checking out the trains schedule online but it seemed rather confusing AND seemed to provide for only 10 mins to get from one platform to another,and I couldn't seem to find on the website the time(s) for alternative trains (in case we miss any connections).
