Should I stop at Interlaken for a night before continuing the Golden Pass ride to Lucern?

My starting journey from Geneva. I read there are three leg of the Golden Pass journey but couldn't find further details on how to travel around it. Will there be time to look around before i abroad the next train if I don't want to stay at Interlaken but Lucern. Thank you very much.

Question about The Golden Pass

There aren't just different legs to the journey, you also have to change trains and train companies. Here's the link to the official site where you can compare schedules and plan your connection times to allow for as much sightseeing as you need: http://www.goldenpass.ch/
