OP: what had you planned to do for two weeks? What types of things would you do if in the US, in NYC or SF for two weeks?

Depending on your circumstances it may be too late to fix this, but my wife and I have learned that we don't really like being in any particular city more than 3-4 days. We've been to most of the major world cities and on some level they're all sort of all the same. I'm a dude and am not really into shopping, though I do like to see food markets and whatever local street market just to watch the people and the life. Since we live in Atlanta, we don't need to see the high end shopping in any given city as many of those retailers also exist at home.

What we have started to do is book a cultural experience when we travel. I've fallen in love with taking cooking classes whenever possible. It's a great way to understand the culture and its a great way to bond with other people, when if they don't speak your language.

I've also learned that its important to stop and smell the roses. I can't define what that may mean to you, but I "accidentally" went to Hakone and there's a sculpture museum that was real interesting and relaxing to walk around. I especially enjoyed the foot bath there where you sit and hot mineral water flows down a trough over your feet. It was one of my best days in Tokyo.

Finally, see if its possible to leave Tokyo.... Maybe you need a change of scenery.
