At least they are cancelling before you get to the site! I've done 2 balloon rides. The 1 in Australia, was booked when we were in a vineyard region and wrongly assumed it would go ahead whilst we were there. Got to site at ridiculous O'clock, they sent up a little weather monitor/flame or something and said its no good and we'd have to try another time. Problem was, that the vineyards were a 3hr drive from where we lived. Twice more, we did this ridiculous drive, leaving at 2am, to be there on time, to be told it wasn't the best of the weather!!!
The one in Egypt was equally early, but I detect far less safety conscious! I recall us floating above a farmers field and him trying to shoo us away! We all had to crouch down and 'brace' then got dragged along the ground, on the side, for sometime. It was fine though, because the sides are high, so as long as you can crouch down, you are inside the actual basket.
I agree with wearing layers, a hat and gloves, but also have a T-shirt underneath incase it does get hot.
Ensure if you have a camera or phone, that its tied around your wrist
Except for the burner noise, it was quiet, peaceful and most enjoyable. Have a fabulous time OP.
