My husband and I were flying out of gate 32 and arrived with plenty of time, but our flight was delayed 2 hours, so we thought we would explore other gate areas for restaurant options. When we took the APM from our gate area to another area, we were FORCED to exit the terminals and could not re-enter the terminal without going through the ENTIRE security process again! By this point the lines were much longer than when we first went through! And while we were in line to go through security we overheard a man and his young daughter approach a TSA agent with the same problem we were having - he left his gate area to go get a coffee somewhere else and was not able to return to the gates at all, and his flight was boarding in 20 minutes! He and his daughter surely missed their flight. And before you ask if the fault is ours, please know that there was NO SIGNAGE ANYWHERE warning us that we would be forced to exit the secure areas when we were trying to move between gates. This is absolutely unacceptable and could be avoided with simple communication and signage, the lack of which has undoubtedly ruined vacations and trips for many travelers. Shame on the Orlando airport!
