Geeteeo400....That leak may be there. I am not trying to change your plans just a note to help you find the leak if it exists, or give even better piece of mind.
Here is the procedure, make sure you have a clean dry surface to park over, use a piece of cardboard under the car if you have to. on a cold engine put on your pressure tester. Warm up the car in the driveway to operating temp, pump up your tester to 15 lbs, put the car where you want it for the night, and shut it off. Make sure the pressure tester says 15 lbs and leave it. Have 2 beers and go to bed.
When you wake up go look under the car, you can do this in your onesie, but you may get some coolant on the feet.
If you have a coolant leak it will be obvious under the car. If no leak. You are good. If you see it trace it back and make the repair.
Now the another way is to put fluorescent in the coolant, they sell it in small bottles at all auto parts stores. You do not need to use the whole bottle, one little shot will color plenty. Do the same pressure test procedure, all night. If the leak is hard to take the dye helps find the source. You need a black light and glasses to see the dye.
Sometimes a small leak can be ez to fix a loose hose clamp, a pin pricked hose. Other times could be bigger issues, but this test will find the leak if there is a leak.
Good advice on the pressure testing. You can typically get one at your local parts store that offers free tool loaners. You simply put a deposit on the tool and when you bring it back, the will credit you your money - so no cost to you.
However, this may test for a leak using the pressure, but what it does not test is your radiator cap. Have had several caps go bad - rubber seal shrinks inside the underside of the cap or the pressure valve in the center has a rubber seal that can also go bad. The pressure valve can also weaken. So just a little enough can escape and then evaporates just as fast because the radiator is hot, so you never actually see the leak, but yet you can smell the anti-freeze.
I would install a new cap and/or check the one you presently have to make sure the cap is correct and seals match the neck on your radiator. The parts books at many stores sell generic one size fits all according to their computer screen when indeed, it is not a one size fits all situation. Made in China and the pressure cap may actually be lower than its rating and allowing pressure to escape.
As pointed out earlier, tighten all hose clamps. They can work just enough to be loose after they cycle a bunch of times - hot & cold. Make sure the clamp is correctly seated past the raised rib on most outlets, and not on the rib or before it. The clamp should be near the rib so as to squeeze the hose and take advantage of the rib to pinch the hose tight. I have been in a hurry and not paid attention where I placed the hose clamp, and sure enough, have just a tiny leak that like the radiator, I could smell the antifreeze, but not see it because it was vaporizing as it leaked out.
A bad heater core is another experience if it is still original. It'll leak/drip and evaporate. Then once you pull the heater core and inspect, sure enough, you can see the corrosion and leak stains.
Just a couple more thoughts.
