Spotting at Brussels


Hi , I am looking to fly to Frankfurt via Brussels from Manchester in or around June 2018. I can get an early flight out of MAN with Brussels Airlines & a flight with Lufthansa from Brussels later that day. Question is has Brussels got a viewing area or an area where spotters / photographers gather ? Is it ok to spot at Brussels due to the recent terror attacks in Belgium /France ? Any help or advice would be gratefully received before I book my flights. Also can anyone recommend a good , cheap hotel close to Frankfurt Airport ?
Many thanks in advance. Mark Harrop
