Thanks for bringing your question to us here at planDisney, Larry!
You'll be arriving at the
Disneyland Resort just in time to experience the Disney California Adventure Park's
Food & Wine Festival. The festival runs from March 1 - April 22, and a great way to enjoy all the flavors is to purchase a sip & savor pass, stroll through the park, and taste away!
Disneyland's
ECV and Wheelchair Rentals are in the esplanade, east of
Disneyland Park's main entrance. I did some research and there is no current discount or special for multi-day rentals. Pricing is subject to change and ECV daily rentals are $60 plus tax with a refundable deposit (not taxed).
If you're staying at a Disneyland Resort hotel, another option to consider is
ScooterBug, Disney's approved mobility rental service. They'll deliver it to your hotel and you can keep it for multiple days. You'll have to confirm if they deliver to the area Good Neighbor hotels if you're not on property, but in my experience, my family members have had ECVs delivered from third parties like ScooterBug.
Well, Larry, I wish you and your wife a wonderful trip filled with many memories and lots of pixie dust!
Magic awaits!
