Who cares what any other Guest at WDW thinks?
What do you think the chances are that you will ever again see
ANY of those people? As folks around my neighborhood say "The chances are slim to none, and Slim just left town." In other words, you have a much better chance of winning the lottery than you do of running into someone you see at WDW.
It's none of their business. And just so you know - 99.9% of them won't pay any attention anyway. They are all too busy posting to Insta, SnapChatting, checking Facebook and tweeting to notice you, your DH or anything else. That's why - no kidding - you have to be extra vigilant driving a wheelchair or ECV at WDW; people are so self-absorbed that they will walk right into you because they aren't paying any attention.
Seriously - your DH on an ECV? He's a non-event at WDW. I promise you. There are, at any given time THOUSANDS of people on
ECVs all over Disney World. I was terrified the first time I had to use an ECV at WDW. I just knew that people would point and laugh and I would be humiliated. Then a weird thing happened.
Nothing.
Me - a 3L (Large, Lovely Lady) on an ECV at WDW was a total non-event. No one treated me any differently. No one made any snarky remarks. Nothing.
Now my medical conditions have sadly advanced to the point where I have my own personal ECV. I get on that thing and RIDE. I smile and wave at everyone like the visiting Princess that I am, and I go on and have a BLAST at WDW. Every. Single. Time. And the very few times I have encountered stupidity in human form, I just smile even bigger, and give them a good 'ol Okie "Bless your heart" (and we all know what *that* means, don't we?) and I go on.
Things will be fine. I promise. Go and have an awesome trip!
