My wife is traveling to MCO next weekend and needs a rental car. She currently has no rental car club memberships, meaning that she would have to stand in line to pick up a car.

My question is: Is there any way to get a club membership FAST so that she can get the expedited service by next weekend? Basically I'm looking for a program that has online sign-up with the ability to make an immediate expedited-service reservation. We live near rental locations for most agencies, so if there is a requirement to sign things in person we can do that this week, as long as it makes that first rental go smoothly.
