Like Ian, I am confused by some of the examples given here, in particular:
Iremos adonde tú quieras, cariño >> We will go where (to whichever restaurant) you want, darling...
... which does involve movement, but despite that it uses 'donde' - with no accent !
And in the short quiz included in this site, I got this question wrong:
We are taking the children to where they can run around freely > Llevamos a los niños ________ puedan corretear libremente…. i.e., I [incorrectly !] chose "adónde" with an accent because it did seem to involve movement … (but no ! - it had to be "adonde").
