Alright, I have awesome experience with this now
We went in early June. I believe the problem started at the beginning of our vacation before we even left our driveway. I picked up my mother's suitcase and put it in back but felt my back do something weird.
At the end of the first day my back was hurting pretty bad but I powered through. I was ok if I crouched down in line or squatted. By the end of the second day I had slowed considerably. By the third day I only made it two hours before I started to bawl and told my family I was going to have to go back to the hotel (but wasn't sure how I'd get there). I literally stood at the base of the Hungry Bear and cried. My husband insisted I get a wheelchair. I was totally against it. He went up to the front and got it and brought it back and demanded I sit. The rest of the vacation went wonderfully. My back got the rest it needed and honestly, the wheelchair saved our vacation.
The worst part about being in a wheelchair was that people don't look where they're going and I had numerous people try to jump over my lap to 'beat us'. That was the worst. All castmembers (minus one grumpy chick..) were SUPER SWEET. They assisted me in and out of the cars where I might've needed some help (I didn't, but they were cute). They treated me with respect and dignity. I ignored everyone in line because it was hard enough for me to swallow my pride enough to use the chair in the first place..if I'd seen someone glare at me I'd crumple. When we went it was crazy busy, so it's doable, trust me!
Don't hold your family back. This is the part that hurt my heart the most. I couldn't do it to them any longer. The chair made EVERYONE happier. EVERYONE. You have a need. Trust me. Ignore anyone who doesn't understand. You and your family do and that's all that matters.
I'm 29 and needed a wheelchair in
Disneyland for my back. How ancient does that make me sound
Oh and for the record, California Adventure is very wheelchair accessible. You can go through just about every line with your party. In Disneyland is where they have you enter at the exits.
