Jewish Holidays

I grew up lighting Chanuka candles inside the house. In my community, the uniform practice is to do so outside. I think that is great, but I miss seeing them inside my house. Is it permitted to light a second chanukia indoors (could it be bal tosif)? If permitted, what is the best way to do it?

A guy who came home late and the only one who could wake up was none other than his father.

Is it better to do netilat lulav in the sukka before one goes to shul or during tefilla (before Hallel)?
