firstly Stephlac, Im happy to hear that it all worked out for you and hopefully you'll forget about the hassels cause of the good time you'll have.

Yes Quito was fun, but was told to go to Santiago, Chile to get a better taste of the Spanish influence in buildings. However, I just booked another trip with AV to Cartegana,Columbia for June, got another point strecther deal with Hilton.
Not only was I able to get all the things that were recommended to do but that was all done with trying to get use to the altitude, Cuzco is higher up and I had no problems there.Just had to walk slower and keep out of the gym. sleeping was a little difficult since I went down with a slight cold that made it harder to sleep.

I hope you got 1st class since coach is usually full and the ONLY thing that the people back there don't have are chickens under their arms.1st is usually over 1/2 empty and the FAs due take care of you.
