Just a tip regarding saving your route from cloud to your local in-flight navigation device (I got caught by this a few time).
Like you I plan using my laptop at home and then save routes to the cloud. I then download from the cloud to my navigation device (Samsung S3 smartphone).
If you have poor or no internet connection at your airfield make sure you have saved your downloaded route (from cloud) to your local device before leaving home.
Otherwise, just as you are ready to go flying, you find you can't access your pre-planned route from the cloud!
