Europe has so much to offer, but in order to get there, allow yourself a full extra day simply for travel.
For example, had to be at the airport for 0800 on Sunday morning, had a 7.5hour stop over in Kuala Lumpur, which was good because we didn't have to rush & could freshen up, have a meal & a drink, & stretch our legs around the huge airport. Then left KL at 2310 to start the 13.5 hour flight to France. ETA being 0630 Monday morning. (Total of 26 hours in transit).
Highlight: AirFrance onboard meals including creamy Camembert & fresh mini baguettes to be enjoyed with a nice red!
