What's the best way to plug the drain on a Vino?/Edgestar?

I've heard of people using pretty much anything. From tape to screws and now paper towels.

I would think tape would be sufficient, but in reality, having the opening is probably not a huge issue.

I haven't plugged mine and my RH stays pretty constant between 65-70.

Try some tape, electrical or duct should work just fine and see if you notice any differences.
