Wow, it's not about "audacity." I said I'm glad Disney is offering multiple different accommodations to meet the needs of people with different disabilities and medical conditions instead of just doing a blanket
DAS accommodation for almost all disabilities. It's not what a lot of people need.
I'm not trying to speak for everyone in the Crohn's community. Everyone's case is different. My uncle, who is now deceased, had severe Crohn's and had part of his colon and intestines removed and had a colostomy bag. When it filled up, they had to stop whatever they were doing to change his bag. Sometimes, he'd have to be late for things because it would happen right before he left to go somewhere! He couldn't help it, and we just had to be flexible. For him, having a line return option would have been great. When needed, he could have let the line and returned to it later when it was a better time.
My dad has Crohn's as well. His symptoms are not as severe as many, but it's enough to make him nervous during travel. For him, to be able to leave the line and return would make a big difference for his WDW vacation. As I said before, he also has prostate cancer, which causes urgent urinary needs. Being able to leave lines and return would help him there, too.
For me, I don't have Crohn's. I have IBS-D. I can go a few days with no symptoms, but then I get a flare up and have to be near a bathroom for hours. I get little to no warning, so the scariest parts of my WDW trip are usually being on the bus. What if it hits me near the start of the bus ride? I can't wait 20 minutes for the bathroom.
For all of us, we'd benefit most from a line return option. I think it's SUCH a great option for people with medical conditions that require emergent bathroom use. However, shortened lines are not the accommodation I (or my dad or uncle) need. That's why I never applied or DAS. How does a shortened line help me if I get struck with abdominal cramps and need to leave immediately to use a bathroom? It doesn't matter if I have 10 minutes left in line, an hour left in line, or am at the loading area. I need to leave.
If you feel like a shortened line does help your child on your trip, then absolutely you can still buy Genie+ to book LL for shorter lines. But if an issue crops up with a bathroom emergency, won't it also be good for your child to be able to leave the line and later return? I'm just glad Disney is working to accommodate the needs of guests instead of just doing blanket DAS passes for most medical conditions and disabilities. In your case, you may benefit from line return, and now that will be available! And if you still need shorter lines, you can still do that buy getting Genie+. So now you actually have two strategies to help!
