Thanks Yukon (living in the Yukon I assume?  I lived there for about 11 years).  They've just worded it in a way that makes it sound incredibly complicated!  So far I've been treating it as I always have or just putting in the amounts for the 2x$600 trips if they don't have a box 32.  As you say, it seems to work. 

One thing though is that, if I used to have a family of four and both parents receive the travel benefit of $2,500 in their box 32, I claimed two trips PER PERSON on each return (as long as they took four trips of course) So I guess that could be considered as something different.  Curious how you would handle one single person's file where the box 32 has $850 in it?
