MUST KNOW when getting tickets here - you will definitely get to go up the tram (in case it sells out from people buying tickets on the day) BUT you will still have to wait in the line of people purchasing tickets AND you will have to wait to go up on the tram...which I did not know. If you buy tickets directly from the Tram website, you will choose a TIME and when you get there you will go right on up at the scheduled time, no waiting around. For example, we had tickets from Viator which meant we would be going up no matter what. BUT when we got there, we had to wait in line with everyone, even people who were just then buying tickets (that line went pretty fast, maybe 20 min). And THEN we had to wait an hour to go up on the tram! I was disappointed, it didn't really do us any good buying these ahead of time. So just be aware
