No. Let's compare my National Emerald Aisle experience at LGA and the Thrifty (same company) equivalent at MCO:

Arrive at LGA. Arrive at the parking garage. A greeter points me to the Emerald Aisle. Choose a car. Drive to the exit booth. Show license. Leave.

Arrive at MCO. Arrive at the parking garage. Blue Chip and Dollar Express members are directed to a booth. There will be 2 adjacent windows, one for Dollar Express, and the other for Thrifty Blue Chip. A list shows your name. Next to your name is a stall number, or "see agent." If it says a number, you walk to your assigned vehicle. A contract jacket is hanging from the rearview mirror. If you don't like the car, you can choose another one in your category, provided that it does not have a contract already written for someone else.

If the board says "see agent," as in my case, join the line. There'll likely be several inexperienced and unprepared people ahead of you, waiting to speak with the single agent on duty. Bring a book, since they could argue for a long time about what kind of insurance they do or don't need. If you're lucky, like I was, the agent at the adjacent Dollar (or Thrifty) booth will offer to take you next. They will hand you the pre-printed contract jacket sitting on the Thrifty (or Dollar) counter from the next window. Then you are told to go out to the lot. Pick whatever unassigned vehicle (no contract on the mirror) you like in your reserved category, as shown on the wall. Drive to the exit booth. Wait behind a few cars with customers who didn't know what to expect, and already put away their license and contract, in their jacket pocket in the trunk. Show contract and license. Leave.

I would do the Dollar/Thrifty scenario again if the price was right. Otherwise, National is a more efficient process for experienced and prepared customers.
