United World College or other int'l school(s) (Maastricht)

Dear All,
I'm new to Internations. We are an American expat family currently living in Eindhoven for 2 years now. Our daughters attend the International School of Eindhoven, and they are 10 & 16 years old. My husband has been offered a job in Liege, BE, and we are interested in living near Maastricht. Does anyone here have any personal experience with the United World College or the other international school in Maastricht? Would love to hear your thoughts, opinions & advice! Thanks!
