Welcome to MySwissAlps! I would hesitate to book 3 nights in Engelberg in mid April. Things could still be winter-like. That's good if you love snow. But more likely there is no snow in the village, but still enough in higher altitudes to prevent you from hiking there. Mount Titlis will be nice and snowy, but you can reach it from Lucerne too, which is more centrally located. It all depends on your goals and expectations I guess.
Interlaken is not the nicest town in Switzerland in my opinion, but in April it's not so bad for the same reasons as above: it is a good base to explore a wide area, including the Jungfrau region.
The above links offer more details, including activity and hotel suggestions. Just let us know if you have further questions.
