My parent-in-laws lock (close the basement door) the cats in the basement at night. If you don't have a basement then another room with all the essentials could work.
For awhile we locked the cats out of our bedrooms but I missed having them at my feet at night. As someone said below the cats are crazier when springs comes around. They get spring fever just like us. They miss the smells, open windows and so on.
Also someone mentioned not letting them sleep all day and play with them an hour or so before your bed time. I have 2 cats and they are crazy at night if I do not play with them before I go to bed. I try to wake them up throughout the day to so they don't nap too long, that way they are tired at night or at least won't be crazy at night.
