>> i will be switching trains (6 minutes) at Interlaken platform 2A to platform 7.
Arriving at Interlaken Ost at sector A of Platform 2, the first thing you will probably see is stairs down to the underpass for changing platforms.
Walk past the stairs towards sector B, and you will see a ramp on the other side of the underpass, which will be easier to get down with luggage, and with your father.
There is a diagram of Interlaken Ost station attached to my post of Aug 17, 2016 - 10:17 AM on the page below. It shows the stairs and ramps down to the underpass, and where the platforms are:
A 6-minute change here might be a bit tight with your father, especially with luggage and if it is crowded. If you want to generate timetable connections with longer transfer times, use advanced search and change the "Duration of transfer" from "Standard transfer time" to whatever suits you best.
