Having gone through an exercise of validation and re-editing for the
Ottawa area in general, I took away the lesson that a little gap is well
worthwhile in terms of the subsequent pain it avoids. After all, it's
not as if our tools on the ground can actually detect such a discrepancy.

Sebastian,
You should follow Clifford's advice. It is a pain to fix
things that are glued together and should not be.
A parking lot is ADJACENT to a hotel, but it is not part of
the hotel. Also, if one wants to make change to either, they will
have to be unglued. This is quite difficult to do, when, for example,
one wants to change a way that has been glued to an adjacent field.
This is wrong. If two areas are physically adjacent to each other, with
nothing in between, then they should be mapped as such. ie sharing nodes
(or as multipolygon relations, with a shared way).
Don't leave a gap on the map if there isn't actually a gap 'on the ground'.
It might make it a bit trickier to edit, but that's more about knowing
how to use the editor. eg in JOSM middle click to select the other way.
And it makes some editing easier - eg if you adjust the position or
improve the accuracy of the building, its correct that it will also move
the parking.
Note linear ways sharing nodes with areas is a separate issue (eg roads
sharing nodes with fields), I think that should be avoided where possible.
