The flight from Montreal to Puerto Vallarta was delayed by one hour because one engine aboard the antique DC-8 did not start. That gives you a feeling of extreme confidence. We were delayed by an hour. Severe turbulence for the entire flight and the vomit bags were well used. I am sure the pig slop served on this AeroMexico flight exacerbated the puking. A very rough landing. Remind me not to travel on AeroMexico again. A Sunquest rep met several of us and a small group headed to a VW bus to a dearly expensive room at the Sheraton. I was miffed at being given a room on the ground floor with a flooded terrace. Complained to reception and was told to come on down for a room change. Upon approaching the reception area the clerk knew nothing about the room change but a few dollars in his hands reminded him about the the situation with a beautiful room overlooking the ocean the result. A few passengers were puking outside and a pool of vomit had settled nicely behind a potted plant in the lobby. As I was unpacking I realized I had left my passport under a pillow in the rejected room. A surly night clerk took me to the room where in a sigh of relief my passport was recovered. Crashed out to the delectable sell of sea air and the sound of pounding waves.
