IC is WORST Place to Stay in Cali IMHO
well, maybe Aguasblancas or Mojica (slums) are worse.
Not sure why you choose thatHotel (yes I believe it is guest friendly, though the closest I have been is the Italian Restaurant out frront) unless you are going on a marriage agency trip.
If you want to spend that kind of money, the Sofitel, Sheraton and Dann are all WAY better. I like the Torre de Cali and Plaza Versailles better too, but they are cheaper than IC.
Thursday night is happening. Go hit the bars on Avenida Sexta or the Casa de Cerveza. ATMs are the way to go BUT withdrawal limit varies from bank to bank. Bancolombia is best as it gives 400K per withdrawal (most others have 300K limit). NEVER use 200K ATMs (RIPOFF!)
You are going at a great time as the festival is going to be in full swing.
Dress to Impress Works Well in Cali
You can dress more casual but will definitely attract more attention if you look upscale in your dress. Avoid jewelry (so as to not to attract unwanted atention). Later is better in Cali. If your Spanishg is good, try the disco in Torre de cali (particularly convenient if you stay there) Hint.
