what would you suggest for us with our 3 teenage daughters who really just want to sunbathe...I was thinking about 4 or 5 nights in BA and then what???? thanks

For sunbathing I would suggest you wait until summer. It is fall in the southern hemisphere at the moment.

After BA, a trip to the beaches of Argentina, Uruguay, or Brazil would be perfect come December.

If you are looking for teen style action to introduce your daughters to a wider range of activities, after four or five nights in Ba...head to Iguazu Falls.

Take the boat ride under the falls....followed by a half day adventure zip lining and rapelling down the side of a waterfall http://iguazuforest.com/

Stay at the Sheraton. It is the only hotel in the park, which gives you immediate access to the trails around the base of the falls and the top...and to the tram that goes to the Devil's throat. The kids can lounge by the pool at the Sheraton and take in the falls in the distance.

Or, head to the mountains. Llao Llao resort is amazing. Take a half day excursion by boat to explore the lake and islands or go horseback riding or hiking in the area...perfect activities for December.

thanks for the info, I forgot to say we were going at Xmas
