Remember the time you had to wait hours and hours to enter the elevator of the Eifeltower because you were simply not the only one willing to wait .
From the end of this year (2009) it should be possible to book online tickets avoiding you to wait.
Check here for the official website. Tour d’Eiffel
If you do not want to even enter the Eifel Tower you can just buy your souvenirs in the webshop Tour d’Eiffel.
