Hiroshima - Tottori - Shiga - Osaka

Hi Daniel,

I would like to seek your help on my itinerary as follows.
Q1: For Day 6, would it make sense to stay at Osaka and do day trips to Shiga prefecture instead of staying at Kyoto/Otsu?
Q2: I will be purchasing the Kansai Hiroshima pass. When will be a good period to use the pass - would it be Day 4 - Day 8 where most of the intercity travel will happen, and buy single tickets for other trips? Would you recommend other passes that could cover my trip (ie. more days covered as compared to the K-H pass which is valid only for 5 days)? Or would Day 2 - 6 on K-H pass and another pass to cover Day 7 - 10 make sense?

Day 1 (20 Oct): Fly in Hiroshima (Stay in Hiroshima City)
Day 2 (21 Oct): Hiroshima – Miyajima day trip
Day 3 (22 Oct): Hiroshima city tour
Day 4 (23 Oct): Hiroshima to Tottori (Stay near Tottori station)
Day 5 (24 Oct) : Explore Tottori
Day 6 (25 Oct): Tottori to Kyoto / Otsu (Stay in Kyoto / Otsu City?)
Day 7 (26 Oct): Explore Shiga (Hikone & Nagahama)
Day 8 (27 Oct): Kyoto/Otsu to Osaka
Day 9 (28 Oct): Osaka – Kobe day trip
Day 10 (29 Oct): Osaka – Himeji day tip
Day 11 (30 Oct): Fly out Osaka

Thank you!
