That's the issue..... you are hoping everything including the floor and tray are bang on level which they most probably won't be. Work out a few different layouts and see what works best as the first tile. More often than not a half to 3/4 tile works best.
Just use a polymer modified cement adhesive with good initial grab.
Is this your first tiling venture?
