Corolla 2011 Vibration

Hi! I just “tuned up” my car thinking it’d fix the vibration. But it didn’t, somehow still vibrates, not too bad but it’s noticeable. I’m planning to drive about 1,900 miles in two days and I’m unsure if it’s safe to do so. Based on this thread it seems to be the engine or transmission mounts? Does anyone know if it’s safe to drive that much (I’ll take 4 days for that trip)? Also how much would it be to fix the mounts?
