Re: Has anyone visited the Hombu Dojo?
There`s a hotel that rents by the month just down the street from the Aikikai Honbu if that is where you mean. Maybe if you contact Honbu they can help you. Or maybe people who are there now can take a look and give you the name and number.
As far as experiences, I am remembering this French guy I met who saved up money to visit and happened to pick a week that the dojo was closed. I recommend looking at the dojo calendar before coming,
