Change of plans

I had a change of mind while in Costa Rica, as beautiful as it was, and it was, I´ve decided to move my way south and do a few things there. Planning this trip has been fun, cause the truth it not too much planning was put into it, I just knew I wanted to go. One thing I´ve had to keep in mind of was the weather, as fast as it changes at home, holds true for what i´m going to expect further south. I´m right now hanging out in Guayaquil, Ecuador, 2nd largest town to Quito (capital), and 1st in revenue, or something like that, due to tourism: new int´l airport and la embarcaderra, hub out to the Galapagos Islands. I mention the weather because I´m going to make my way to Machu Picchu, it´s cold, getting colder.
Along the way, I´ve used numerous sites to understand the route, buses are widespread throughout, getting the correct name of the bus line takes a bit. From Central to South, had to fly in, travel agents recommendations, along with every other site I checked out. I hear that to get through to Colombia from Ecuador is more feasible, i´m checking that out, safety first.
