The "space" issue is really overplayed. The difference is so minimal. If you need more space then a CX-5 then you need to move up a class to the bigger SUVs...not a CRV.
In our case the extra space (when compared to a real SUV like a Suburban or Expedition) is only needed maybe once in every 3-4 years or so. If anything a 2nd trip would suffice. 1st world problems
