I'm having surgery and wont be able to walk long distances. Do they offer wheel chairs? Will I need a doctor note? We already had our trip planned before this surgery

You have to rent a scooter, there is a cost, not sure how much...

I know that they have scooters there. I believe they rent them. But I'm not sure. But they allow wheelchairs and actually have a special line for you.

I'm not too sure about whether they provide wheelchairs or not.. However if you bring your own I'm sure you'll have no troubles with the park nor will you require a doctor's note. <- this is not 100% so it's better to wait for a few other answers
