Its one thing if those meetings are for meeting a new client or discussing a new project with an existing one, but it is another thing altogether for (eg) weekly hour+ long status meetings.

^^ This. One of the biggest ways to boost billings is to be consistently -- even relentlessly -- easy to do business with. That applies to billing and time tracking as well.

Tightly scope, fix a fee against that scope and set your rate high enough that you can accommodate dumb meetings, the occasional on-site, etc.

When I was consulting full-time, I never even charged for travel because that removed a potential objection from out-of-market clients. But my rate? It was at the upper end of the range.
