Pack n play

I read a lot of posts about having cribs...has anyone had a pack n play that they play in or nap in? i know they are small...but just thinking something easier to put away when company is over! i cant find weight limits when i google them...but thought this could be a fun thing to have...was just curious if anyone else has tried?

Pack and plays will not work because the bottom isn't a solid piece of wood it's more like a heavy cardboard. So probably isn't an option.
