Do you have the number for your current supplier with you?
They may have a 24 hr contact number and may be ble to rush ship to you..
Care Medical is one of the companies that rents
scooter, but they are a full service medical supply company, so may be able to help you.

I found a link to the Animus company. The company website says they are there for you 24 hours a day. They may be able to figure out where to get some locally.

also to their web store with an 800 number:

They have options for ordering from them - it says they ship in 10 days if they have to go thru insurance or 2-3 days if by credit card. They may be able to do more rush in an urgent situation.
Do you have anyone who can get into your house and do an overnight delivery to you?
Try one of the local hospitals. Maybe talk to Social Work if they work on weekends or to Pharmacy. They would not be able to sell to you unless they have a retail pharmacy, but should be able to point you to some places.
The concierge at the resort can be helpful with getting places or getting things sent to you - and may even have had this question before.
Good luck - hope one of these suggestions works or someone who actually pumps or lives in the area has some better suggestions. Let us know.
