G, I'll say "Amen" to all of the above.
While you hope for success, plan for failure. With incontinence you will not be disappointed.
While your incontinence is intermittent, it is difficult to judge how frequently you will have an episode during foreign travel with a change of food, hours, etc.
Take diapers and plenty of boosters and plastic pants. Double diaper at night with a booster plus absorbent pads under the sheet.
And don't forget disposal bags!
Do some research with Google so that you know where you can restock, as required. If you do not speak French, write down the French translation for critical incontinence supplies.
Then just have a great vacation in Paris and enjoy all the wine without worrying about it!
I have my vacation travel next month on a cruse ship and am going through the same planning process.
