I am traveling for work. My company sent me my hotel reservation. It says "one adult" on it. I am bringing my wife. Do I need to sneak her into the room, or will I be fine?
At a normal, business-oriented hotel in the US with rooms intended for double occupancy, this is not usually a problem.
However, we don't know which hotel you're staying at or their policy, so the best thing to do would be to call the front desk and check. It's possible that there could be a difference in cost, such as if breakfast is included in the room rate, and they'd be able to give you that information in advance so you aren't surprised.
