Paris Pass Card

I came across the Paris Pass while browsing the net looking for a hotel in Paris. I saved so much money on my trip thanks to the pass. I saved time too, as I didn't have to queue up for most museums or sights. I paid €70 (not sure if this is the current charge) for a two day pass.
Included in the pass are a bus tour and a boat tour. All museums accept the pass and the majority grant immediate entry, meaning you get to skip the queues. You also get a metro ticket,valid as long as your pass and a booklet of vouchers for various shop and restaurants around the city, for exmple a free sundae at the Hard Rock Cafè.
The only thing I found I had to pay for was my ticket up the Eiffel Tower. I would recommend the 2 day pass to anyone who wants to see the main sights, but the 3 day to anyone who wants to spend long lenghts of time in museums.
The pass can be ordered and pre-paid on- before your trip and then collected at The Hard Rock when you arrive.
