Paris airport shuttle - what's the diff?
 

I made a reservation with Shuttle Inter last night, but in looking at a couple other services I notice a considerable price difference. For example, Paris Shuttle (www.parishuttle.com) lists $24 one way for two people and Paris Bluvan is around $43, I think.

Is that because Shuttle Inter is 'private' meaning only the two of us would be in the shuttle and it would take us directly to our apt?

That's right. £24 is not for a private shuttle. If there is somebody else with you, maybe you will have to wait for your hotel, if the hotel of the others is closer than yours. Or if they are late, you will have to wait for them. That's the big difference. Otherwise for a private shuttle, it's more expensive.
This shuttle service in Paris is only a private one and the rate is cheap.

Beward.... I understand that some of these shared shuttle services are not reliable. Ask for recommendations.

Just got back from Paris last night and used Shuttle-Inter for the RT CDG-Paris. We were really pleased with the service; it was 55 euro each way and just the three of us in the shuttle, which was a roomy van. The driver was waiting for us at CDG, even though our plane was over a half hour early. We asked for an 8:00 a,m, pick up for the return, and he was there when we exited our apt. yesterday morning.

It is more expensive than a shared shuttle, of course, but IMO, it's worth the extra money.

Thanks y'all.

I finally figured it out last night and see that when it comes to a private shuttle, Shuttler Inter is the least expensive of the three at 55e. The other two were around 67e and 85e.

Here in Dallas, it's about $35-40 one way to the airport from my area, which is about a 45 minute trip, so I'm struggling with paying $75 for one-way.

But, we're in Paris only for a short while, so I'm thinking I'd rather pay a little more for the reliability of a private, direct shuttle versus trying to manuever RER/Metro and potentially waste precious time. For now, we'll keep the Shuttle Inter reservation and I'll let you know how it works out in the end and whether or not we felt it was the best choice for us.

Two weeks to go.
