Where should I go?

So running a small business alone has a lot of downfalls, including the fact that I never get to travel because I am the only one here and I have to be open! I only close once a year, during Mardi Gras, because the streets are impassable and the city is basically one big party. So I have a six day window in February to travel and I am already planning my next escape. Where should I go?

Australia

I have many blogging pals to drop in on in Australia, it will be summer in February, I have never been there and I love the design going on in Australia right now. However, the flight alone will eat up two days of travel time and I don't have a close friend in the area to go and do things with.

Buenos Aires

I have always wanted to visit Buenos Aires, I love the architecture and interior design aesthetic, I think the shopping will be well priced, I speak the language, and the nightlife will be spectacular. However, it could be slightly dangerous for a girl alone and I don't know anyone locally.

Florence, Italy

I have already been to Florence and it is one of my fave cities in the world (along with Bangkok). I am loving the modern design mixed with old world architecture, and could happily spend four days just sitting in a cafe and walking the streets. I would love to shop and visit museums and could probably have a hot romance if I wanted, since I love Italian men and Italian men love me. hahaha Only downside is the travel time and once again, I don't know anyone locally and have already been there.

Istanbul

I have longed to visit Istanbul for a very long time. One of my all time fave design firms (Autoban) is located there, and Antony Todd opened a store there last year. It has amazing sights (like the Hagia Sofia) and shopping. I also have a friend who is a local and could show me around and possibly I could stay for free. Only downside here is the travel time and cost of flight is pretty expensive...

Paris

I just saw Midnight in Paris (great movie!) and it reminded me of how much I love this city. I have already been there, and don't really want to revisit places I have already been until I go to the others, but I am greatly influenced by Parisian designers and there are many I would love to visit in person. Also, Paris is a great city to see alone (or with a lover) so I could wander the flea markets for hours. However, I don't have a local friend and I have already been.

Mexico City

Mexico City is probably my vote. It is the closest, so the flying won't eat into my travel time too much. I lived in Mexico for years so I am very comfortable there, and am fluent in Spanish. I love the big city and all the museums and shops and restaurants. There are some really awesome modern hotels that are very inexpensive, and I have a friend locally who could travel with me! Can't really think of a downside to this one, except it is not as exotic or exciting as the others.

So what do you think? Where should my next trip be? Since I didn't get my condo I have some money to burn and I love to travel by myself and be adventurous. Help me decide!
