” On the other hand, is it proper chinuch to set up water bowls by their beds just during the next 2 weeks of the campaign? ”

I think it is.
first of all the idea of taking on chumros to get close to Hashem is bought in halcha for example avoiding pas palter during Asers Yemei Teshuva, even though all year the person isnt makpid.

Secondly I think when Kids are motivated (even if through prizes/contest) to take something extra on, it is important to support that motivation even if we all know it wont last.

The exception would be if you have some specific hakpadah NOT to wash by bed, either because you have a specific hanaga davka not to (not just that you rely on shitos that say isnt neccesary) or if not practical due to spilling (which you indicate) In thiose situations I agree the point is too was negel vasser and sink is fine
