Have a full day guided charter for 2 coming up in the gulf of mexico.Got lucky,I won it,something I could never afford.

Is it realistic to spend a few hours of it to try to learn flyfishing?I've never even held a fly rod,but can hold my own with other types of fishing.Don't want to waste much time on a once in a lifetime trip for me,but the guide has the gear and it my be a good time to try it out.

Just the basics of casting and the mechanics of learning it.
