Bless your mum, my mum has been going to Disney since it very 1st opened and has gone every other yr since,
The last 2 trips she had to give in and use an ECV due to knee surgery & bad hips plus s leaky valve which effects her breathing,which in no way shape or form did she want to do!
My mum is 80 this yr & at 1st 3 yrs ago she got on with the ECV fine , she actually really enjoyed it as we stayed at Akl and it was a very long walk to our room at night,
This last trip however she really struggled it was so busy and people walked infront of her plus kids run out from no where, it scared her so much she lost her nerve and for the 1st wk of our trip she stayed at our resort
not going to the parks which upset myself & my boys!
After that wk Dh. & myself decided we was going to rent a wheelchair from Disney and push her as we did not want her missing out anymore, she was much happier not scared and was able to carry on for the next 2 wks
I'm telling you this because at. 88 in a busy park I would hate for her to have this problem,
I would suggest if you do go down this route as others have suggested that
1. She goes and practices on
ECVs in the supermarket to see how she copes,
2.go at quite times to start and then build up to the busiest time so she knows what it's like to have people walk on front of you etc
Also think wether you could push her is a manual chair, I'm 5ft nothing and 8stone 6 I found it relatively easy to push my. 12 & half stone mum around as its smooth and flat.
Just to add my mum did Peter Pan, pirates etc and with the help of me or Dh managed the moving walkway just fine, just be prepared to act quickly,
