I am going to be flying into Guayaquil and spending a week helping out in Manta. After we are done I hope to be able to go to Quito as the only other place I have seen is Machala. I plan on spending about 5 more days and figure I will fly at least one way since it looks like flights are less than $75. one way. I had thought about bus or train but not sure if train available all the way. It is hard to find this info out. Also the budget is fairly limited. Any advise?
