You're not going to like where they put you.  The public viewing areas
are a *long* way from the pad.

A sophisticated technique known as "wild-ass guess".

In December of 1972, I watched the launch of Apollo 17 from the closest public viewing area - about 10 miles away - and we still might have needed some kind of pass to get that close. It was a night launch and the shuttle is now from that same complex. With a 50mm lens, the launch pad was a tiny white little speck. The photo we came away with was a time exposure of the launch. It showed the path, and a few cloud layers illuminated by the rocket engines.

Exposure with Ektachrome 64 was probably about f/5.6 of 5/8.

For this kind of photo, a really long lens may not add that much.
