Hello
Finally after waiting 7 years I am about to embark on obtaining my PPL (12hrs built in 99, 00)

I work away on business and am considering flying in the following three locations;
1. Ireland
2. England
3. Belgium (Brussels area preffered)
Is it possible for me to complete a JAA PPL in multiple countries (obviously completing my test in one particular area - probably Ireland).
I am okay for schools in Ireland and UK, but can anyone recommend a school in Belgium?
Also, it is an issue changing between aircraft types?
