Not exactly on the same page, but im currently completing my NPPL (M). I completed 12 hours here in england, before hopping across to portugal for 10 hours...
I found the experience, amazing, (2 diffrent instructors over there), because of the benefit of having 3 instructors, who picked up on and worked on something different!
I had to get used to the location (Reference points, abort points and airspace) very quickly to be able to gain from my training.
From a professional aspect (Further on from the NPPL) im not sure that its seen as good to have studied at various different schools, because they like u to have stuck to one firm. (From what ive heard).
Now back in the UK and carrying on
All the best with your training.
