I just use the spare 1/2 bath and keep that lid up all the time, unless we're expecting guests.
So the only times I use the master bath toliet is first thing in the morning when I'm sitting down for a read and the morning constitutional or in the middle of the night when I don't want to turn on a light anyway.
We also the leave the lids down to keep the dogs out. Our dogs would probably stay out anyway, but I had a dog in college that would put his front paws in the toliet when he drank out of it, what a mess
