Transport in Paris

Easy to use, app is simple and provides good info on train routes etc. A bit pricey at first, but you if you don’t have definite plans and prebooked train tickets months before, will recommend getting this to avoid variable prices.

A rail pass is truly excellent, especially during discount seasons. If your general itinerary is set, a pass valid for several trips within a month is very convenient. Additionally, once you factor in the TGV reservation fee, it's almost the same as the original price, but it's still more cost-effective than booking at the last minute.

i have booked with klook and there’s no issue. The voucher is recognized by the bus service and it is faster, you dont need to line up

Excellent service by Wang, very punctual and helpful, much appreciated!
