Hi All,
It took three days, but I FINALLY secured our Eiffel Tower tickets for July and wanted to share a tip/hack I found that helped.
Tickets go on sale at midnight Paris time - which is a perfectly reasonable 6pm here on the East Coast. Except, whenever I tried a dummy run in the weeks leading up to this, the 60-days-out date was never available. It turns out your DEVICE needs to be set to Paris time - in my case, my computer. I set it to Paris time yesterday and at 6pmEST/MidnightCET, it worked! Of course, the website malfunctioned between me putting tickets in my basket and actually paying for them, but it finally worked tonight! (I'll note this was AFTER I thought they went on sale at 830am Paris time and got up at 2:20am only to find everything was sold out.)
Hope this helps!!
