we are traveling with someone who has recently been diagnosed with irritable bowel syndrome. I don't know much about it but frequent bath room visits are a must. Do they offer the assistance card for this type of ailment?
We use a DAS for my DD to help with the sensory and other issues related to autism, but I have IBS. If I'm having a flare up, the DAS won't help me. Even with the DAS, there is the wait in the FP line and then the length of the ride. That's far too long for me if I'm having IBS trouble. To help with the IBS, I have to use other strategies, like those mentioned by @tobikaye above.
Luckily, since my IBS is strongly influenced by stress, I tend to have far fewer flare ups on vacation. I usually plan for downtime immediately after meals to give me time to assess if I'm going to have an issue and to make a couple stops into the bathroom before heading to a ride or show. I also use Imodium and, as crazy as it might sound, peppermint candies. I started using the Starlight peppermint candies as a natural alternative to the medication Levsin when I was pregnant with my DD, and I found they really worked without as many side effects. I haven't had a prescription for Levsin for over 10 years now, but I carry peppermints with me at all times. If I start to feel an IBS attack coming on, I'll suck on a peppermint (or two or three in a row) and it usually stops the cramping and keeps me from having to run for the bathroom.
I would disagree and think it is possible a DAS would help with IBS. My son has toileting accidents (only at the Disney parks, never at home), and I mean DISASTERS at times, #2. I need to get him out of line ASAP, this is not like a baby diaper, trust me. Because he uses a Convaid chair on the lines, it is almost impossible to back him out of the lines, if we are deep into a long line. While there are lines for FP+, of course, getting off of them is generally easier than the regular line. (PS my son is non verbal, so no warning for these incidents, perhaps an adult (without my son's mental handicaps) would not need this, of course). But all this depends on individual, and a discussion with the CMs.
We spent 10 days at Disney World this December. I was issued a DAS pass for my IBS and it totally changed the scope of our trip. I no longer had to pass up rides with the super long lines, and was able to rest during the wait times (my IBS is triggered by anxiety and exhaustion). Cast members were amazing, and often issued return times or 10 to 20 minutes regardless of current wait time. It made our trip 100% more enjoyable! This is why I don't mind spending the money for Disney, because they handle every situation so exceptionally well and I get to enjoy my vacation to the fullest.
