Cant stand heights!!!. Fine when flying. Ex PPl, gliders, some aeros etc. NO PROBLEM!. That's 'cos there is no perspective. I got vertigo on the London Eye!. My wife stood on the edge of Table Mountain. I couldn't go within 20 yards of the edge!!. Some super advice from everybody here. SO hope you enjoy your trip! It may become addictive, you never know........ Best wishes.
