How often do you go with him/her? DH has a bunch of travel opportunities coming up and I would like to go with him as much as possible, but I'm not sure what's really feasible. Is it too much to go on 4 trips a year? What about one trip a month? We for sure have 4 trips to go on this year, but I'm debating whether the kids and I should join him for the rest of his trips.
