Hi,
Thanks for all the advice. Much appreciated.
I have heard about the overtourism in kyoto ( and avoiding golden week in kyoto)
So many places to see , so little time

I have booked a 2nd night at the Conrad Tokyo and cancelling the 1 night stay at Hilton yokohama
on my previous visits to Hiroshima I have flown back to tokyo ( I spent an hour at the sankeien garden beside the airport after check in and it was beautiful ( being almost the only person in the park) but will consider the shinkansen ( although it is Tuesday of golden week, If i book in advance it should be ok ( and probably send my large suitcase in advance to tokyo by the luggage delivery service)
Regards
TBS
