“Dear PoPville,

I am a little stuck and wondered if you could help. My daughter turns 5 in June and we want to have a birthday party at a 3rd party vendor in the city and not in MD or VA. The zoo has great parties but is a little expensive. We are looking into the building museum too. I wondered if you had suggestions for any other ideas that we could explore that wouldn’t be astronomical.”
