You're on the right track: vacation plans, travel arrangements, potential injury that makes travel problematic...hmm, what else might help to "trigger" the call, heh, heh.
Maybe plan a special romantic dinner/date night with DH, start a (small) home renovation, fake putting your house on the market and buying a new one (lots of annoying open houses, realtor appts, etc.) invite family to come to visit/stay over...surely all these things can combine to get you the good news you so richly deserve!
