I've seen so many reviews on lenses and lost any hope of committing which one to get.

Ideally I want lens that's good for everything but those do not exist. This is why I need your help picking something that works best for me. I would like lens to be able to take landscapes, some night shots something that can take on vacations (walk around lens) defiantly want wide angle lens. This is why 17-40L is something I’ve been looking at for a long time. However then, I came across 16-35 2.8L II, 17-55 f2.8 IS and EF 20mm 2.8 USM

Right now I have Canon T1i with 50mm 1.8 prime and two kit lenses 18-55 and 55-250. Since T1i is getting old I've been thinking about getting Canon EOS 70D (later this year, which most likely I’ll get with kit lens 18-135). But that’s in the future. I want to get new lens that I can take on upcoming vacation (in 2 weeks).

Can you please suggest what best to take that won’t be an overkill on T1i or 70D.

Please help!

EF 17-40 f/4L USM is sub-optimal on "crop" bodies like your T1i and anticipated 70D.

i would disagree with you and the ones who have the same opinion here are a couple of galleries that are taken entirely with 17-40mm f4/40D. i am not sure even if you have or used the 17-40 mm f4:

I used a 17~40 on a crop body (20D) before there were good alternatives available. And yes, you can produce perfectly satisfactory images with it. But there are now far better choices for crop factor use, like the EF-S 17~55/2.8 and the EF-S 15~85. The 17~40 does best what it was designed for, as an ultra-wide zoom on FF, which is how I now use it.
