Hey, sorry to hear your camera's acting up right when you need it for that vacation :) It actually sounds like the autofocus system might be the culprit, could be something like a stuck lens mechanism or dust inside that's messing with the focus motor. Since you've already tried cleaning the outside and resetting everything, it might be an internal issue that needs a closer look. If your camera isn't super old or a basic model, repairing it could definitely be worth it, especially with a tight budget, rather than shelling out for a new one.
If you're feeling handy and want to try a DIY fix, you could open it up to check for any obvious problems like debris or loose parts. For that, I'd recommend the precision screwdriver kit because it comes with magnetic tips that make handling tiny screws easier and a variety of bits perfect for electronics like cameras :) It's got tools for prying open cases without damage, which could help you get to the focus assembly and maybe clean or realign it yourself.
One thing is it might not have every exotic bit for super specialized cameras, but for most digital ones, it should do the trick. Overall, if you're comfortable with tinkering, this could save you repair shop costs and get you those clear pics in time for your trip; otherwise, a pro repair might be safer if the camera's still under warranty or something.
Before opening it up try a few non-invasive fixes: make sure it’s not in macro or manual focus, set a single center AF point, aim at a high-contrast edge in good light, and run the zoom from wide to tele while half-pressing focus. Power-cycle with the lens facing down and gently tap around the lens barrel, and use a hand bulb blower at the lens gap to clear grit; avoid canned air and don’t force the lens. If it still hunts or misses focus, the lens/AF unit is likely failing; repairs on compacts/bridge cameras often run around $80–200 and can exceed the value of an older model, so get a written estimate and compare it to a used replacement which, yeah... i’d skip a DIY teardown unless the camera is already a write-off, because ribbon cables and alignment shims are easy to damage.
