Maybe I'm having a senior moment, lol, but I could have sworn Trop has a garage. Last year my daughter and her family were in town, and we took the kids to see the Titanic exhibit, which was then at the Trop. I believe my son-in-law parked in a garage that was located on the Strip side, south of the Tropicana intersection (we entered from the Strip). After going to the exhibit, we left the car there, walked across the street, and took the tram from Excalibur to Mandalay Bay to see the Shark Reef.
Am I imagining this garage? Or is it gone?
