No disrespect meant but I wouldn't do this most especially for a trip to WDW. If you aren't doing these already you have no idea how your body will handle them.
I still remember when I foolishly, without medical advice, thought "oh I'll do women's one a day vitamins" and then got horrible severe stomach pain. Turns out it's a common side effect on the iron content of it and if you already consume enough iron in your diet it can do more harm than good. There are people who consume too much vitamins for their body and it has negative health consequences when doing so something of which in the U.S. we have a problem with taking supplements without the advice or direction of our doctors.
On a probiotic that's messing with your gut and it's not the time to test out how your body handles it between possible bloating, gas and upset stomach. Even 2 weeks out.
Plus you don't know a person's medical situation so recommending something like this IMO while I'm sure you're thinking well it's just not something I would recommend doing. It may be necessary for you but completely unnecessary for someone else to do it (or they may be taking stuff already based on their personal health). It's also overkill IMO for a trip to WDW .
