We will be taking my mother and father to DW with us in August. My Dad suffers from a very sever form of Rheumatitis. He normally can walk for about 30 minutes, more than that and he has trouble walking the rest of the day. We will be gone for ten days so I am very concerned about making the whole trip pleasant for him, one day with too much and he will be out for the rest of the trip. We have been discussing the use of an ECV during our trip buy he is very reluctant. This has been hard for him to deal with. I have read on several threads that sometimes the ECV rentals run out and I want to make sure that if in the middle of the day he decides he needs one, he can get one. What would be the best way to handle this? I have thought about renting one from a third party but I'm not sure who to use. Any opinions & suggestions, experiences, etc. would be greatly appreciated!
