This will be my fourth year incubating in airtight containers and it works well. I usually check once a week, but I'd be happy to leave them for a fortnight.
If you're concerned about drips from the lid, put a loose layer of damp sphagnum moss over the eggs. This will both prevent drips from falling directly onto the eggs and have the double benefit of keeping the humidity up around the eggs.
Have a good break!
