this seems to be harder than expected :-)
Ofcourse, we want to see as much as possible during our time in Japan. That being said, we are used to a tight schedule when traveling, but we do not want to rush through everything.
I tried to modify the schedule a bit, taking into account all of your recommendations. Can you guys please have another look at this to see if the order is a bit 'logical'?
We opted to travel directly to Kyoto when arriving in Tokyo after our international flight. I know it will be a long day, but we hope to arrive in Kyoto late afternoon. That way, we can drop our bags in the hotel, go out for something to eat and have an early night, hopefully bright and ready to start the next morning in Kyoto.
We also dropped 1 day of Tokyo in favor of the rest of the schedule. If necessary, we can also drop 1 day Kyoto to add to the rest of the schedule.
