Another big difference is price. We rented a minivan from Thrifty last year for 8 days for around $200.00. No one else even came close. They are offsite and yes, it probably took a little longer. But, we arrived late at night so we weren't planning on doing anything except getting the car and heading to our rental home. The money we saved could be spent toward something else. Another, note, if you make reservations now, keep checking back with your rental company. Sometimes they run specials and if you catch one, you can modify your reservation to save even more. Hope this helps.
