My Dh has a work assignment in Buenos Aires and needs to spend 3.5 weeks there in April/early May. I am thinking of sending going to visit him sans kids. He'll be working probably 1/2 the time, 1/4 spending time/"schmoozing" with colleagues, and the rest to spend with me

Obviously room will be comped, and his flights will be as well, so I'll just be paying for my own flight tickets and our/my entertainment.
1. is Buenos Aires "worth it"? The flight tickets are more expensive than I for some reason thought they'd be...~$1000 ish
2. If so, suggestions for activities to do both solo and with my husband? We're pretty flexible and have diverse interests.
