Travel Plans Headache

Nice, Spanish ingenuity fucking me over . I have Granada all planned out more or less. The problem is that getting to Granada is starting to be a pain. I can't seem to either order the bus tickets that I need to get to Madrid or change the train tickets to an earlier time so I can take the group bus and not have to wait half a day for the train. I guess I can always sight see Madrid while I'm silently cursing the incompetence of Spanish businesses when it come to the web. Although, their vending machines are top notch with freezing units.
