This might indeed be a good plan 1. a stay in Lucerne (or surroundings) and 2. a stay in Interlaken (or surroundings).
From Lucerne you may want to visit the Rigi
. If you want to make a longer (day) trip, visiting the Titlis
via Engelberg may be worth considering.
If you wish you can travel between Lucerne and Interlaken (or the other way round) by the GoldenPass Line
(a panoramic train: making reservations are necessary in that case).
From Interlaken many people want to visit Jungfraujoch
. Another possibility, especially during beautiful weather, is Schilthorn
: on a clear day you may see the Mont Blanc from there.
If weather conditions are not so good you could visit the Aare gorge near Meiringen.
For more tips please look at the day trips
and hiking possibilities
in the Bernese Oberland.
I hope this anwers your questions.
