Honestly, it's not that difficult to use a squatty pottie. It's not my favorite kind of toilet - but it serves the need. There are foot panels on either side of the opening so that you know right where to position yourself. Be sure to take a pack of tissues, as there will never be paper available.

If you use the toilets at the nice hotels and restaurants, and minimize your fluid intake during the day, you'll minimize the number of times you need to face this issue.
