Have fibromyalgia and arthritis and neck problem. Can't decide if I should rent a car from the airport because I am afraid of bumpy or uncomfortable busses at Disney. Also I haven't used an ecv but think I need one. Can you get them in the trunk of your car if I do rent a car? Is it true you need to rent one offsite because they aren't readily available late morning. Do most people with disabilities rent cars from the airport or do they use the limo services? It seems like there are so many difficult decisions to make about the easiest and most comfortable way to get around. The decision making is spoiling the excitement of going for me. I'm also 64 and don't want to spoil the experience for my husband who doesn't always understand my disability. I would appreciate any advice on anything. Thank you so much. Lene
