We didn't walk all the way up,
The tower has three levels for visitors. Tickets can be purchased to ascend either on stairs or lifts to the first and second levels. The walk to the first level is over 300 steps, as is the walk from the first to the second level. The third and highest level is accessible only by lift. Both the first and second levels feature restaurants.
I think we only did the first level-- I don't really remember.
No, it must have been up to the second level, because we stopped when the only option was elevators and I refused to stand in line. I really don't remember. I was a bit out of breath, but was also in very good shape at the time- so we might have gone up to the second level.
I sure don't remember 300 steps per level, though, but I was young and strong back then. I wouldn't have remembered the strain unless it was truly terrible. I don't remember getting tickets, either. Maybe that's been implemented since then?
That was our first vacation together, and we hadn't figured out that you really ought to have people you know in the photos you take, so 90% of the pictures we took are of famous landmarks and objects, with absolutely nothing personal about them at all.
Might as well be poorly done travel guide pics. We did better in Barbados in our next vacation a couple of decades later. 90% of those photos are about our family in a strange place, rather than just about the strange place itself.
