As well, I've never been to Paris, France and beheld the real Eiffel Tower. But this was worth the $10 just for the photos and the view. I got some awesome photos from the top and I did appreciate that we were allowed to stay up there as long as we pleased once up.
Yes... the elevator is packed to capacity.
Yes... it's romantic. A guy proposed to his girlfriend the night I was there and it was the cutest thing ever.
Yes... it's got an incredible view and from what it seems a great vantage point to look down at the Bellagio Fountain show... but for some reason the night we were there the show was experiencing delays or cancellations or something because we waited around for about half an hour and got nothing (normally the fountain show happens every 15 minutes).
And it's best to go up at night, if you ask me. I can't imagine it being better during the day... at night the whole city is lit up and it's amazing.
