All of this greeter stuff seems unnessicarily complicated to me.
It's one thing for a towncar or limo driver to stand at the escalators if they have a reservation from a specific client. The towncar companies have no presence in the terminal, no counters, no signage, no way for their clients to find the cars other than the driver standing at the escalators with a placard; of course, I am in favor of strictly enforcing the regs regarding where they stand, and the regs prohibiting solicitation.
Taxi drivers are in a slightly different boat. Since they never have a specific fare to wait for, they are restricted to waiting with their cabs, in a specific area of the airport. Again, the regs are there to prevent drivers from harassing people who are fresh off the plane, looking for fares, and I am in favor of strictly enforcing them. But since cabbies can't stand around in the terminal, there should be clear signage directing passengers to the taxi stands. Personally, I don't think the signage is clear enough; I've been to MCO a couple of dozen times, spent many hours there, and know the teminal pretty well, and I couldn't tell you where to get a taxi other than "Level 1, with the ground transportation".
Mears and DME have counters in the terminal. I see no need for greeters of any kind for DME or Mears; after all, Mears has been operating for decades without greeters, and they have built up a very successful business. Mears has been allocated a specific group of bus stops, and a specific length of counter space, and they operate just fine - why should DME, which is a very similar service, be any different? I'll say this - the signage is not adequate. On my recent trip I rented from
Alamo, whose counter is not far from the DME counter, and I saw the DME counter from a distance, but I had to squint to tell what it actually was.
Ditto for the car rental companies. They have counter space and garage space; they have never felt the need for greeters of any kind in other areas of the terminal, nor have I ever seen the need for them.
But again, the signage is insufficient; if you happen to come onto Level 1 toward the middle of the building, you don't know which direction to walk to find your rental car company, DME, Mears, or the taxi stands. Yes, there are signs, but they are just not good enough.
I would prefer to see a map of Level 1, showing the location of each car company, DME, Mears, taxi stands, and hotel shuttle buses, displayed prominently at the bottom of each escalator. A good enough map would eliminate the need for greeters of any kind; people arriving at the Mears, DME, or rental car counters could be directed into the proper queues by the various companies' employees (which the rental companies and the airlines do when it's crowded), and then all of this greeter and solicitation stuff would become a moot point.
