Breakfast at hotels – is it a good idea? Also where to stay for 2 nights before flying out of HND?

I am going to Japan for 17 nights at the beginning of October. I’m staying in Tokyo(5 nights) Hakone (2) Kyoto (6) Hiroshima (2) then back to ? Before flying out? Should I stay in Tokyo but different area? Staying in Asakusa when I get there. Should I stay in another city? Planning on buying souvenirs.

Also I’ve booked the hotel breakfasts where I’m staying. I thought that way I can get some food inside me before heading out for the day. However, I’m reading about tourists leaving their accommodation early in the day to visit tourist sites before they get busy. Will eating breakfast at the hotel delay that. Are most hotel breakfasts the same and I’ll get bored with the food? I’m guessing I can cancel some if I choose

Thanks!
