Yay, good for you. Free roaming bunnies are lots of fun – you never know exactly where they are and what they are up to. You sit down to relax and unwind and suddenly out of nowhere they are all over you, or you walk to the bathroom only to find that the hallway is being used as a racing area…oh, well, and then the noises sometimes coming from another room giving you a clear indication that somebunny is chewing something they shouldn’t
I would be slightly concerned with an intact bunny in the bedroom, but that is only based on my own experience and may not cause problems in your case.
Also, do make sure that they have something of theirs, now that they won’t have a cage, eg. Maze Haven or something else they can use as a private retreat. Also, if they need a timeout from your children. I found that mine needed a cage. When I took it away from them, they would mark everywhere, but as soon as it was back, they were back to good old litter habits.
