How about a Valentines day package at one of the top hotels in town... Im pretty sure you can get an all inclusive deal on a niced dinner and a suite for the apres-dinnes hostilities...
Check the Sofitel Arroyo, the Alvear, the Faena and the Hilton for details... Im sure they have something prepared for the ocassion.
Yes... it will be an 'investment' of sorts, but think of the credit card miles you will get...
