We used the FLL app today to know how many available parking spaces there was in which garage so we can plan accordingly and go directly where there was spaces. We got there and went directly to Hibiscus garage saying there was 29 parking spaces available on the roof and a handful on other below floors, which we skipped to not waste time on finding the last one on those floors. Got to the roof and everyone is double parked, parked in fire lanes, parked on the road, in corners where theres no parking. We started being nervous because Palm garage was already full and we were rerouted to Hibiscus and Cypress. We decided to go to Cypress because there was 999 parking spaces but we had to take the shuttle to our terminal. Once we got to the garage, there was a staff member there and we told him that there was no spots available and the app said there was. He said “Oh yea.. the app never works…” Do not rely on the app for parking, if you are nervous to not find parking, save yourself the stress and Uber or park at the hotels where they provide free shuttles.
