I am a HUGE Illuminations lover. HUGE. It's the only nighttime show I will watch. I say no. Go the the back of World Showcase around Germany through Japan. There will be plenty of spots along the rail just 15-30 minutes before Illuminations. Germany is our favorite because there are a lot of food and drink places to grab something before the show. Plus - bathrooms. After the show, we slowly walk around to Norway, take a bathroom break (trust me, bathrooms are my friend at Disney World) and have almost no one in the ladies' room, then still slowly walk to the front of Epcot, head towards the buses, and the longest I've had to wait to SIT on a bus to Pop Century is 10 minutes. No FastPass required.
