Other Car Rental Programs (ie. Alamo, Enterprise) - Long term Tampa rental

Any recommendations for a car rental company in Tampa, Fl airport for a Dec 30 - March 2 timeframe with my spose added as an extra driver. Primary driver is 62 years old. Would renting by the month and renewing the contract be cheaper?

It seems that flying from British Columbia to Tampa is cheaper than driving. Thank you in advance.

In a situation like this I would call a few Enterprise offices and ask to speak to an Assistant or Branch Manager. Tell them what you're looking for and say you'd like to negotiate a monthly rate. Offices love a high utilization and this will put a car on rent for quite some time.
