Hope the assessment goes well, and sorry to hear that the plan may not work out this year. But, ever the optimist as I am, never say never, as something may change or turn up to allow the trip, whether it be a change in circumstance or a kind offer, and things can always be arranged at short notice to get out there. So, plan on not going hard to accept though it is, but if things change such that you can, accept that too..
