DC is one of my favorite cities! It’s so fun. If you’re looking for a fun place to go out, U street is super cool and fun! DC has awesome places to eat too, museums are all free or inexpensive. Some you do need to do a reserve pass for - totally worth it. Georgetown is amazing to visit too! It’s about a four hour drive from central Jersey with traffic, or you could take a train from Newark. Cannot recommend the city enough.
