I came up in London finance, where a “work trip” is mostly a carry-on, a client dinner and an early flight home. This is the Boston version I'd hand a colleague: hotels near where the meetings actually are (Back Bay, the Financial District and Seaport), a coffee spot for the pre-meeting, a power lunch, a steakhouse for the client and a bar for after. Plus a free hour worth taking and what to pack, because Boston weather has not read your calendar invite. Swap notes in the comments if you've got a better client-dinner spot.
