My friend and I spent 5 days in BA in March. I always watch the TA forums before I travel to get information and occasionally ask a question. This is my first time to contribute. I will touch on some things that I see frequently on the forum and share our experiences.
First, thanks so much for the information on Xoom. This was easy and our exchange rate was much better than we would have received anywhere else. Please be aware that all the offices are closed on Sunday. I missed this fact and we spent a good bit of time traveling from location to location before we determined that we would wait until Monday to pick up our money.
We rode the HoHo bus even though this was our third trip to BA. This system is different from any other city that I have visited since you must start at the main location. There are no tickets sold at the different stops. It is a good way to see the city and decide where you want to spend time.
We had absolutely no problem with taxi drivers. All were polite, efficient and charged only the metered rate and always offered change. It was almost hard to tip the driver.
We were in San Telmo and Boca at two different occasions and felt absolutely safe. Both of these areas offer great photo ops, street entertainment and food. A great place to have a drink and people watch.
We did the trip to Colonia de Sacremento with absolutely no problem. We rented a golf cart at the airport and traveled all over the city - old and new with no problem. If you have covered everything in BA, take the trip but cover BA before spending a day on this.
We rode the train to Tigre and came back by boat. As a part of the ticket price for the boat returning to BA, we were given tickets on the HoHo bus. I was surprised that Tigre is much larger than I expected and a very pretty city.
I would encourage any traveler to make these trips without being a part of a tour. The cost is a fraction of the tour price and you are in total control of your time.
We were in San Telmo and Boca twice. These are my two favorite areas in BA.
My favorite meal was breakfast at the Alvear Palace Hotel. It was expensive but the food was fabulous, the service was superb and the surroundings are beautiful. It as great fun to linger over coffee, people watch and plan the day.
BA is a vibrant, friendly and interesting city. My fear after following the recent posts was that safety was questionable. My friend and I are in our mid 60's and there was never a time that we did not feel safe. A little common sense used when traveling is your most valuable tool...I will be in BA again....Thanks to all the DEs and other contributors who spend their time helping others plan their dream vacations and patiently answer repeated questions about hotels and taxis....
