Long term car rental

Hi,

I’m looking for a long term car rental services.
Me and my wife just got blessed with a couple kf twin babies, but unfortunately being twins they were born preterm.
They need to stay for a month or more at the hospital so I’m looking for any long term car rental services so we can go to the hosoital everyday and deliver mother’s milk.

I have a Times membership but not sure if that is the most economical.

Thank you!
