I think adding your name might be a good idea in this case. It lends some distinction and credibility to your business as if you have already been operating for a while.

I would go with Falk Custom Adventures and then perhaps develop a tagline/slogan to complement your name which could help better define what Falk Custom Adventures is all about.

I would do some research to make sure that your name(Falk)is not being used by another travel-related business if you haven't already done so.

Go for it... Roger
