Another option, instead of the elasticated folding type, would be a telescopic cane. They will go down fairly small, and there isn't the risk of them 'reassembling' themselves on a sharp bend. They will fit on the floor of most ride cars, though for some of the more sedate ones, I will lean it on the seat between myself and my partner (some rides, like HM, don't have much to enclose the foot area, so I worry about it slipping out. It probably won't, but I'm a worrier!)
I use a wheelchair most of the time now, but I always keep my telescopic cane tucked in beside me, so I can use it of I need to get up or transfer. Just make sure that you screw it tight before you lean on it, as otherwise it is rather surprising when it suddenly 'shrinks'!
I would suggest you take the phone numbers of a few external
ECV / wheelchair rental companies, just in case you find you need one (see the FAQ thread). Or the people on the concierge desk will be able to give you their numbers when you're there. Stability issues can be very tiring, especially when you're doing a lot of moving about, standing and sitting, and are out in the heat. If you find that you're not enjoying yourself, because of constantly battling with your condition, don't be afraid to use the help of an ECV or wheelchair, to make your trip more fun
Have a great trip!
