One more try. There are 2 lounges at MCO. There are 2 TSA checkpoints at MCO. One checkpoint is for gates 1-69. Once you are through that you can take either people mover, to gates 1-29 or to 30-69. You can go to the lounge in the 1-29 area, take a tram back and catch the tram to the other gates 30-whatever on that side. No extra TSA involved. They will not have any questions to ask. Simple.
The other security checkpoint is for gates 70-129. Again, once you are past security you can go either way. The lounge is in the 70-99 side, the SW gates 100-129. No additional security needed or TSA questions. However, half of the 70-99 gates are for international arrivals and you would not want to get on that side of the people mover after leaving the lounge because it would take you outside of security. If you pay attention and get on the correct tram back to the gates 100-129 you are fine. If taking 2 quick trams is not worth it to you, fine. I don't care.
My first time last week at the smaller lounge on the American side was interesting. There was a small (15 min) waiting list but I had extra time. The bartender basically gave me a bottomless gin & tonic until I told him to stop. Salad, sandwiches, decent soup, a quieter place to wait, all worth it to me.
