1. Nothing to about but take a taxi anyway. I take the RER from CDG into Paris but want to agree that you should take a TAXI in Paris upon your arrival into Europe. Traffic will be very light and it will be a much more pleasant introduction. You'll have plenty of time to explore the trains when it's not so late and your not so exhausted from flying.
If you feel you must take the RER in, then at least get on an express.

2. Yes - get the day pass (or a 32-day pass if you are there 3 days).

3. Yes, one of several.

4. Yes, one of several.

5. It's a bit much for one day, but you always have the next day if you don't make it - how many days are you in Rome?

I meant to say: 1. Nothing to worry about...

Duh! ...or a 3 day pass...

I wonder what part of "We intend to take RER B" people don't understand. I think it's rather obvious that a taxi would be marginally more convenient, but what's the real difference between sitting in a train seat for 40 minutes and sitting in a car seat? And is that difference really worth $50?

I posted previously about not overplanning, although the times I have been there we are always on the go seeing things and what not. I would absolutely do rome in your time frame it is worth it. My comment was more of a reminder not to forget about the little pieces of europe, we all miss on our way to the big stuff. And don't forget the afternoon sex.

about Rome: I tend to think that doing all of that in one day is quite a lot, but if that's all the time you have, go for it! Also, Campo dei Fiori is a nice nightlife place, too.

Congrats on your marriage! Have a wonderful honeymoon!

Campo dei Fiori. Yes, of course! I had forgotten about it.
