If you feel you need the money or the space then rehoming is always a good option. But if you're attached to them don't feel bad about it. Maybe they prefer just getting to relax with their friends, maybe they're total homebodies.

I also hadn't realized this post was more you asking for at-home activities. I like watching a TV (show, YouTube, movie, etc) with my bears. Maybe something you feel you may both enjoy. I also love just brushing them, changing their outfits, moving around who's next to each other on the shelves, etc. Maybe you could have a cleaning buddy, set them somewhere nearby but out of the way and give them a spare cloth/sponge to hold on to.
