It is definitely worth doing but it's not worth it if it's freezing cold outside. Wait for warmer months and try your best to go when crowds are minimal. The ride up with a reservation was very quick and easy, but to get down took quite a very long time. This was unfortunate considering how chilly it was up there. Mainly lots of school classes attending on groups. The 3rd floor view is worth the extra money. You can see for ages.
