Kids’ joint bedroom is now STUFFED with 3 twin beds. How acceptable is this?

I have 3 boys, ages 6, 5 and 4. They decided 1-2 years ago that they wanted to all share a bedroom. This worked out perfectly at first as they all had toddler beds, there was plenty of space. Today we just moved in the third and final twin-size bed.. and when I tell you, this room is packed. the length of the longest walls is exactly the width of 3 twin size bed frames. My husband and I will not be able to walk anywhere in this room. How terrible is this? The kids do not mind AT ALL but I’m nervous if anybody came to the house it would look bad on our part.
