Huge hugs

! It sounds to me like your DH is worrying because he doesn't want anyone to say or do anything which might upset
you during the trip. I know that my partner tends to feel things 'on my behalf' a lot, and he gets most upset when he can see that I'm stressed or miserable. Maybe if you have a bit of a talk to him about it, and both try and be as open as possible with your feelings, that might help him relax a bit (I know it's not always easy getting guys to talk about their feelings, especially if they think that it might upset you, but it's worth a try.
You might want to put some kind of weight on the seat of your chair when you're pushing, to stop it tipping over. Your balance is likely to be more compromised than normal in the tiring and over-stimulating world of Disney, so you'll need to take extra care. Putting the family backpack on the seat will hopefully be enough to stop the chair tipping backwards if you suddenly put more weight on the handles (yup, voice of experience talking here

). If you need the bag to be heavier when on the seat, and lighter when it's being carried, you can put a few large water bottles in it, which you can fill and empty as needed (also means you have something to drink in line!).
As to fighting the looks, I find that people are a lot friendlier if your chair is decorated up. I guess it's that they spend so long looking at all the cool stuff on your chair, that they don't have time to play the 'judgment game'

. Anything like ribbons, tinsel, beads or fabric can be wrapped around the frame or through the wheel spokes nice and easily; the Spokey-Dokes they sell for kids' bikes will also fit on standard spokes of a self-propelling chair; you can print up signs for the back of the chair with Disney characters or slogans on (if you go for paper, make sure to laminate it!); and you can even make your own seat and cushion covers, if you're good at sewing. For my last Disney trip, I managed to find a set of solar-powered outdoor fairy lights, which I wrapped all around the frame of the chair. I also had those flashing LED necklaces wrapped through the spokes of each large wheel, and we told people that I was an experimental mini light parade

.
No matter how cool you make your chair look, or how much you're wobbling when you walk, or how much time you spend in the chair, there will be idiots who will be thinking stupid little thoughts in their heads. Thankfully, most of them keep them there, locked away in their heads, but there will be the odd jerk who wants to let you know how they feel. I've not yet had anyone actually say anything to me, but I have noticed some of the looks and tuts and other such unspoken comments. For these prats, you need to employ that wonderful sense of humour your hubby has. My fella and I have found that we have much more fun when we laugh at these idiots, rather than taking them seriously. One of my favourites was when I was wheeling fast down a hill (very few crowds, and all perfectly controlled, of course) and someone tutted at me. I then shouted to James that I just got tutted at for having too much fun, because obviously real wheelchair users all look miserable the whole time!
Another one we enjoy, is laughing at people who treat me like $£*& when I'm in the chair, by leaning over me, barging me, shoving me out the way, etc etc. We often joke that I should lick the next person who leans over me, but I'm worried that I might catch 'stupid'. Another fun one is to wave madly at them and go "Help, have I turned invisible again?!". Yup, I'm an evil wheelchair user

.
We also have the 'Moron Scale' for rating the people who cut me up in my chair. It ranges from 1: "slightly dim move, but understandable with the Disney magic", to 5: "leaping in front of the chair then stopping dead, and glaring when you hit them". Just yell out the numbers when you find them, and they won't have a clue what you're talking about!
At the end of the day, only you and your family know what you need, and only the opinions of you and your family matter. I know that that's a heck of a lot easier to say than it is to accept, but it's an important thing to remember. I've heard a statistic that states that approximately 83% of long-term wheelchair users are partially mobile, so if that's true, you're certainly not in the minority. Also lot of people use mobility aids at Disney, who wouldn't need them normally, because there is just so much walking in Disney. Before I developed my disability, I spent quite a few Disney trips in a wheelchair, due to ankle injuries, though I didn't need one in my day-to-day life.
OK, this is all slightly garbled, but basically - go along and have fun! Most of the people there won't even give you a second look, as they'll be too busy having fun. Those who do decide to pass judgment on you are morons, and are not worthy of your time and attention.
Hope you have a great trip!
