I'm sure they are, but it would be best to leave them home with grandparents.
DC is like going to the keys, a tropical get away.
It's kinda hard to keep that atmosphere when a little 2-3 year old is running around crying. Little ones have no idea what DC is. They have no clue you're trying to relax. So they do what any 2-3 year old would do, and that's run all over the place and then cry when they don't get their way.
