MOMA is well worth a visit, and if you're short on cash, has free entry between 4pm-8pm on Friday nights. It does get very crowded though...
For ladies I would definitely recommend finding some slightly nicer than normal black flats... I bought some in Prague for super cheap and still wear them all the time!
Definitely worth doing if you are in any way interested in Ancient Rome - the guide is a wealth of knowledge.
