After spending approximately $40,000 for a 3 week stay at the George V (in my dreams “;-)”, I spent some time at the RATP website calculating whether I should buy an unlimited pass or a “carnet” and replenish it as needed. At this moment a carnet goes for 13,30€. A 1 day unlimited pass costs 10,55€, so it seems as if buying a pass is a better deal. However, if you’re spending time actually visiting Paris rather than madly scampering about, it might make more sense to grab a bunch of individual tickets that you can use **any day**.
Here’s the pricing table for unlimited travel passes as of today.
Paris Centre will get you everywhere any self respecting tourist wants to go. I noticed they include prices for children <<les enfants>>. The footnote indicates that for RATP purposes childhood ends at 10 years (sigh).
I’m suggesting that 4 or 6 bus voyages a day will get you there and back and somewhere else too. My calculation looks like this. 1,33€ per carnet ticket x 6 (max) trips = ~8€ which is < 10,55€. If you save ~2,55€ a day, you’ll be able to afford to stay at the George V in less than 40 years!
As much as I love using the bus system, I love being in Paris more. BTW, the tickets and pass work for the Metro and RER too, but you **really should** take the bus. Allons-y!
