I remember reading a while ago about somebody taking a shuttle from the airport to La Tour Centre Ville, or from a bus station or something like that, but no further information was given. Does anyone know how to catch the shuttle, if one exists?

You can take a bus right downtown. After deplaning and gathering your baggage. There is a sign that says Busses. You will see a big sign with bus numbers and where they go. The maps are available on the Web too. A Cap is flat rate probably 40.00.

ooh that sounds like an awesome tour!

there is a shuttle that will take you to the bus station and then from thier you can take another shuttle to the hotel.... At least I think that is how it works.... I think it costs about 20 bucks round trip....

I ended up taking a taxi because I couldn't find the shuttle I paid about 30 bucks for one way

$22.75 return!!

Just as you leave the arrivals area there is a kiosk, just to the left as I recall where you purchase the tickets. You can buy 1 way or round trip, round trip is a bit cheaper. The actual bus is located just outside. It wil take you to the train station downtown. From there you will transfer to a smaller bus where it will take you to your hotel. The transfer bus is included in the fee.

When you leave you need to make a reservation for the transfer bus to take you back to the train station to catch the airport shuttle. I got the front desk to do that for me. Can't recall how long it took, but I would think about an hr for the whole process.

yeah, thats how it works .. I couldn't quite remember

if you need to leave early in the morning you need to let the front desk at the hotel know ahead of time.... i didn't and ended up having to take a taxi back to the airport again
