Translation of peninsula in Spanish

The four of us ate dinner at this cozy place. As always, we ate meat. After desert we headed to a night club, when my wife started to feel a little dizzy. She blamed the wine, but i had a bad feeling.
We were considering flying to the same region again: we thought of going to Brazil, Venezuela or Guatemala. We were asking a lot of friends on their travel experiences to these countries.
Although it was a beautiful region and a very lovely town it reminded me to much of home and I decided that I wanted to move on. We called Aerolinias Argentinas very early to book a flight for the same day.
