We flew from Finland to Frankfurt (Germany) and rented a car.
The last night we had in France happened to be the midsummer feast in Finland (the most luminous time of the year), so we celebrated it at our cottage in Lumigny with champagne and snails.

For Disneyland we had two-day tickets and it was well worth it! There were a lot to do and explore and we had time to visit the best attractions again.

Paris is breath-taking. The 'Tour Eiffel' is magnificent and the views from there are incredible. Our kids loved it and we had lots of discussions about it for a long time.
The traffic is marvellous! ;-) It's very simple: if there's some empty space, take it. If there's not, go there and you'll have room for your car... Don't mind if you're not on the correct lane - nobody even knows where the heck the lanes are in the first place, and if you need to go in certain direction, just go. That's that and nothing more complicated...
